Abstract


Land is the material basis of human survival and development, and it is definitive role for human survival. With the growth of population and social economy, the land demand is growing in Jiujiang, which more highlights the scarcity of land. In the premise of protection and improvement of ecological environment, in order to moderately develop mild slope of low hill, gradually improve its security protection for food and ecological security, improve construction supply ability, and protect sound and rapid development of economy and society, the protection, utilization and development of mild slope of low hill need to be overall arranged in space and time.In this article, the number and distribution of mild slope of low hill were ascertained based on the spatial analysis function of MapGIS. Then, farming and building land suitability evaluation were held respectively. Finally, utilization countermeasures of farming and building land were put forward respectively. Its aims are to provide references for scientific and rational planning and using mild slope of low hill.In this paper, the main conclusions are as follows:(1) Under the support of the software MapGIS, and according to the connotation mild slope of low hill, the resources of mild slope of low hill were calculated by using land use status map, slope map and elevation map of the year of2010. The total area of mild slope of low hill is1183383.45hectares.(2) With the help of the spatial analysis function of MapGIS, farming land suitability evaluation units were determined by using land use status map and soil map of Jiujiang in the year of2010. Then, farming land suitability evaluation index and weight were determined by the using the method of Delphi (Delphi) and analytic hierarchy process (AHP) respectively. The total farming land area of mild slope of low hill is1141112.08hectares, which includes that422311.21hectares of arable land,397455.95hectares of garden land, and321344.92hectares of woodland.(3) With the help of the spatial analysis function of MapGIS, building land suitability evaluation units were determined by using land use status map and land type map of Jiujiang in the year of2010. Then, building land suitability evaluation index and weight were determined by the using the method of Delphi (Delphi) and analytic hierarchy process (AHP) respectively. The total building land area of mild slope of low hill is42271.37hectares
