    Recently,serious forest decreasing,land degradation,environmental pollution,biodiversity losing,especially carbon dioxide concentration increasing and greenhouse effect have become the most crucial global environmental change problems. The concentration of the atmospheric CO2,one of the most important greenhouse gases,witnessed an increasing process since the beginning of industrialization,it increased from its pre-industrial value of 280 ppmv to its present value of 366 ppmv. It has been proved that human activities,including fossil fuel burning,cement production,and land-use change,have severely disrupted the model of the carbon cycle,thereby altering the climate system and affecting the processes and mechanisms in terrestrial ecosystems. Understanding the consequences of these changes in the coming decades is critical for the formulation of political,economic,energy,and security policies. Thus carbon cycle study in global scale has attaracted more and more attention currently. Forest biomass storage approximates 90% of the biomass in terrestrial ecosystems. To assess precisely the role forest playing in global carbon and understand the role forest ecology system playing in carbon cycle,an increasingly effort has been made worldwide to study the carbon dynamic more accurately. In this paper,several methods to estimate the carbon stored in forests were discussed. They are forest sample site inventory method,model modeling method and remote sensing method. The existing problems of using these methods are analyzed. Moreover,some problems unsettled in carbon cycle and development tendency are specified concisely.

    This paper regards the unique building pattern of experiment building in Nanjing Agricultural University as an observation spot;meanwhile the daily maximum temperature, minimum temperature and mean temperature of the lawn inside and outside of the experiment building were measured respectively. The results indicate that because of the special building pattern, the difference in minimum temperature on sunny days is more than 4 ℃ between the building and the open space. However the difference in temperature during the cloudy and rainy days is minor, being generally less than 2 ℃. When the cold air comes in from the North, the difference in temperature often rises rapidly, this makes the daytime minimum temperature of the lawn inside the experiment building 4℃ higher than that of the open space. As the minimum temperature of the lawn outside of the experiment building reaches the critical low temperature of the orange tree at-4 ℃, the temperature of the lawn intra building still keeps at about 0℃. Just because of this reason, if we are to grow oranges under the same condition as outside of the experiment building, the oranges will not grow well;however, orange can grow very well under the same climate condition as that of the lawn inside of the experiment building. In other words, the microclimate has even caused the transformation of the distribution of the plant species. The mean differences in temperature are different at different time intervals of a day, the difference in mean temperature is the highest at 14:00h at noon, being 1.7℃;the next is at 08:00h in the morning and at 02:00h at night, being 1.3 ℃;and the lowest is at 20:00h, being 0.9 ℃. The pattern of urban architecture exerts a greatest influence on the minimum temperature in a day. The object of this paper is to emphasize the impact of the pattern of urban architecture on microclimate and to arouse public attention. Finally suggestion is given on how to rationally utilize urban buildings.

    This paper analyzes traditional streaming-based method and discusses the advantages and disadvantages of octree scene organization. And then the paper introduces loose octree into dynamic scene organization and puts forward the concept of data dispatching pipeline. In addition, according to this concept, the corresponding method of dynamic dispatching based on coarse-granular pages and fine-granular tiles is put forward. It is a real-time dispatching method based on out-of-core terrain which uses coarse-granular pages to organize terrain and fine-granular tiles to embroider terrain, so it avoids reading from out-of-core terrain frequently and realizes delicate dispatch for the data of large scope terrain scene. There are some advantages of our method as following:by analyzing the dispatching process into each stage and frame of pipeline, it decreases the "explosive mode" memory and I/O request and ensuring stationarity;by making use of stages of data dispatching pipeline to manage the life cycle of page and tile, it avoids unnecessary costs of state transferring of page and tile;and by using memory pool to manage the allocation and recycle of memory, it has higher utilization efficiency to memory.

    Some large objects, such as roads, bridges, tunnels and so on, have strip characteristics in spatial structure, so vehicle-borne laser scanning system has great advantage in gathering 3D information of these large strip objects. Laser scanners can record all the detectable data of the ground objects when gathering information and acquiring many scan lines, each scan line data in fact is equivalent to a cross section of the strip object, and these scan lines can divide the object into many narrow regions. If we build triangular mesh with two adjacent scan lines data, the corresponding narrow region will be overlapped accurately by the triangular mesh. All of the triangular meshes were merged into one big triangular mesh naturally without any extra operation and the whole large strip object is accurately described by this big triangular mesh. Topological relations were built automatically. Dynamic update was limited in the limited range and fit for rapid modeling.

    The development of digital terrain analysis based on DEM is helpful for the simulation of solar radiation in rugged area.However the effect of DEM scale causes great uncertainty to the simulation.Taking loess hilly area and Qingling Mountain as test area,this paper studies the relationship between simulated astronomic radiation and DEM resolution through simulating daily,monthly and yearly astronomic radiation based on a serial of DEMs with different resolutions.The experimental result shows that simulated astronomic radiation increases gradually with the decrease of DEM resolution.When DEM grid cell size is greater than the relative heights of the test area,the radiation simulated is stable and the terrain factors such as slope gradient and aspect do not affect on the redistribution of solar radiation any more.In loess hilly area,when DEM grid cell sizes close to 1 000m the relative error of the annual astronomic radiation is about 22%,exceeding the winter’s radiation in this area.In Qingling mountainous area,errors are relative small and the maximum relative error is 17.8%.In a word,the impacts of DEM resolution on the simulation of the solar radiation are much greater in hilly area than in the mountainous area.

    Transmission of schistosomiasis has direct or indirect relation with geographic environment, constituting a cut-in of application of geo-informatics to this field. This paper firstly reviewed the existent problems in the study of schistosomiasis habitat, gave a geo-multi-analysis on the schistosomiasis transmission mechanism, studied out the prerequisite conditions and general procedures for the application of geo-informatics to the schistosomiasis research. The environmental features of the schistosomiasis habitat and the principles of application of geo-informatics to it were then included, from which several apocalyptic insights were gained, suggested that the uncertainty in the process of monitoring schistosomiasis habitat is extremely complicated. So it is necessary to introduce current advanced remote sensing technique (like artificial intelligence, expert system, knowledge-driven classification, etc.) to improve the monitoring accuracy. The key factors in the schistosomiasis transmission are positive snail and cercaria density in infecting water, hence use should be made of correlation analysis and spatial modeling assisted by GIS thematic data and field survey data to conduct spatial simulation of the schistosomiasis-susceptible areas.

    The use of an index system is an important approach for land use monitoring and evaluation. In order to meet the requirement of land use evaluation in the national development zones, a new index system was proposed, which consists of three perspectives: land use degree, structure and efficiency. Based on the index system, a comprehensive evaluation model was built by using standard deviation coefficient to determine the weights of the evaluation indices. The index system and the evaluation model were tested in the land use evaluation for 10 national economic and technological development zones, and a quantitative score was drawn for comprehensive evaluation in each zone. The results show that the approach is effective and exercisable.

    Water is the most active factor in the world and presents all kinds of configurations,which formed over a long period of time. We can open out the pattern of temporal and spatial change and forecast the trend of feature. Geo-informatic Tupu synthesizes the concision of landscape image and the abstraction of mathematics model,which is the result of combining the special technology and product of traditional study. Based on the principle of Geo-informatic Tupu and its expression,we studied water area change in southwest of Songnen Plain through remote sensing data obtained in 1979 and 2001,adopting remote sensing (RS) and geographic information system(GIS) technology. The research indicated that the total area of water in southwest of Songnen Plain is 2018.22km2 in 1979,while in 2001 the area reduced to 1 488.12km2 with a dynamic degree of 1.01%. The main influencing factor is land desertification,grassland degradation and human overexploitation. Then we calculated several landscape indexes to present the variation characteristics of water through the theory of Tupu and reflect the relativity and math relationship of water elements. This paper expresses and retrieves the dynamic variation of water in the study area using RS and GIS technology.
