Abstract

Abstract: As an important basic work of the main function division, spatial development suitability evaluation is important in the process of urbanization in coordination. Especially in the coordinated development of space, it has an irreplaceable advantage, in solving the problem of development out of control and disorderly competition. Based on the data of geographic national information data, large-scale basic surveying and mapping data, industry special data and statistical data, combined with GIS analysis and analytic hierarchy process, this paper constructs a suitable evaluation system of spatial development for Yulin city, and analyzes the local suitability of space development. The results show that the most and more suitable area for exploitation and development in Yulin are mainly distributed in the northwest, accounting for 18.4% of the total area. The most unfavorable and unsuitable areas are mainly distributed in the southeast of Yulin, accounting for 39.86% and 41.75% of the total area respectively. The above results are mainly due to the distribution of a large number of mountains, complex terrain and geological disasters in southeastern of Yulin. At the same time, the region's per capita available water resources is relatively limited, which led to difficulty in the development.

Key words: land spatial development suitability, geographic national conditions, space analysis
