摘要:

新疆维吾尔族自治区地处中国西北边陲,研究该区宜耕土地资源的空间分布,对促进其土地资源合理开发,确保国家耕地安全和粮食安全具有重大现实意义。本文基于多源自然地理要素,对新疆土地资源的耕作适宜性进行GIS多级评价。首先,选取地形、气候、土壤和生态4要素共10个宜耕因子,采用综合指数法与极限条件法相结合的评价方法,构建了新疆宜耕土地资源评价模型;然后,将模型结果与基于地貌数据获得的宜耕区域叠加对比,确定对模型结果的分级标准,得到新疆宜耕土地资源的数量、质量及空间分布格局;最后,利用2000、2005和2013年3期土地利用数据,验证了模型的合理性和科学性,同时,通过统计分析找出模型中需进一步完善之处。

Abstract:

Located in the northwest frontier of China, Xinjiang holds an important strategic position. Carrying out a study on the distribution of suitable arable land resources of Xinjiang may have a great significance in promoting the rational development of Xinjiang's land resources and ensuring our country's arable land and food security. Based on multi-source natural geographical data, through building an evaluation model with GIS, this article made a multi-level comprehensive evaluation from the spatial aspect on the suitability of land cultivation in Xinjiang. First of all, choosing 10 indicators from 4 factors including topography, climate condition, edaphic condition and ecological condition, making use of the function of spatial analysis in GIS, and combining comprehensive index method with limiting conditions, this article constructed the evaluation model of arable land resources in Xinjiang, from the standpoint of the suitability of land cultivation. Furthermore, the modeling results were compared with the actual arable area extracted from topography, which would be used to determine the classification standard of the results, so that we can evaluate the quantity, quality and spatial pattern of arable land resources in Xinjiang. At last, using the data of cultivated land resources in 2000, 2005 and 2013 in Xinjiang, the research effectively proved the scientificity and rationality of the evaluation model, and also figured out the necessity for further improvements.
