基于GIS的延安市城郊区土地利用格局优化研究
Study on the optimization of landuse pattern in the suburb of Yan'an city based on GIS
摘要
Abstract
Taking the suburb from Gaopo to Sanshilipu of Yan' an as a case, slope, aspect and relief were extracted from DEM, then combining with landuse pattern, vegetation diversity, surface water, ecological value and other eco-fac-tors, ecological sensitivity and suitability were evaluated by using spatial overlay of spatial analysis in GIS. According to the results, referring to the method of landscape pattern optimization, the study area was devided into four parts including prior development zone, guided development zone, limited development zone, and prohibited development zone. Then the study decided the scale and scope of the development and the construction in accordance with the degree of construction suitability in different zones, thus provided theoretical basis for the optimization and regulation of land use pattern in hilly gully area. The results tell us that prohibited development zone is 10.98 km2, accounting for 53 .80 % of the whole study area, so the study area should give priority to ecological protection, and based on which, some appropriate development activities can be carried out.关键词
