Abstract:

Suitability evaluation of territorial space is the premise and basis for scientific territory space planning, transition of territory space governance mode and creation of high-quality territory spaces. It is of important significance to optimize the development and protection pattern of territory space and perfect subjective functional orientation of regions. Based on literature review, summary, inductive and comparative analysis, this study reviewed conceptual connotation, development course, evaluation units, evaluation index system, evaluation method, modern technologies and application framework of suitability evaluation of territory space development. It pointed out shortages of existing studies and it suggested to deepening research fields and directions. At present, the theory and practice of suitability evaluation of territorial space have made great breakthrough, and the evaluation index system has formed a more comprehensive system, and the evaluation methods show a trend of diversification. Although many studies have discussed suitability evaluation of territory space development, there are inadequate attentions to multi-objective collaborative evaluation of territory space development. Specifically, it fails to achieve satisfying results in refining of evaluation index system, multi-scale comprehensive study and intelligence level of evaluation methods. The firstly, the construction of the index system is lack of uniformity and standardization. Different studies are based on different goals and perspectives, and the index systems constructed are obviously different. Different scholars have great differences in the evaluation of the same area, which affects the objectivity of the evaluation results. The basic information data can not meet the evaluation requirements of the whole area, the whole element and the whole temporal phase. The ability of Geo-information science and technology to support "smart evaluation" is insufficient. Secondly, in the existing studies, the micro scale evaluation is the majority, the macro scale evaluation is less, and the multi-scale comprehensive evaluation research is very rare. Finally, there is a lack of integration and application of existing evaluation methods for the suitability of territorial space development with intelligent frontier technologies such as spatiotemporal big data, cloud computing, unmanned aerial vehicles, Internet of Things, and 5G network, and there is a huge space for future mining. In future, we need to do well in the following aspects. The firstly, it is suggested to carry out more multi-scale suitability evaluations, promote the integration, transformation and transmission of multi-scale evaluation. Secondly, improve standardization and refining of evaluation index system. Attach importance to the positioning of regional development, pay attention to the special needs and industrial advantages of regional development. In addition, follow the pace of "smart society" construction closely, strengthen the integration and application of earth information technology and Internet, database, cloud computing and other emerging technologies, promote the formulation of land and space multi-source big data and the effective integration of suitability evaluation system; couple GIS, remote sensing and big data to carry out information mining, and provide strong technical support for "smart evaluation".
