基于GIS的牡丹江市主城区建设用地适宜性评价

根据研究区内地质环境特征，选取地貌类型、地面坡度、地下水位埋深、地下水腐蚀性、地基承载力、土体压缩模量和地质灾害易发性7个评价指标，利用层次分析法（AHP）和GIS空间分析对主城区建设用地适宜性进行了评价分析.结果表明，牡丹江市主城区建设用地适宜性良好，适宜区和较适宜区占主城区总面积的58.2%，并以主城区南部区域地质环境最为优越，建议牡丹江市适度向南发展，同时做好生态环境和永久基本农田的保护工作.

SUITABILITY EVALUATION OF CONSTRUCTION LAND IN MAIN URBAN AREA OF MUDANJIANG CITY BASED ON GIS

According to the geological environment characteristics of the study area, seven indexes are selected, including geomorphic types, surface slope, groundwater depth, groundwater corrosivity, foundation bearing capacity, soil compression modulus and geohazard susceptibility, to evaluate the suitability of construction land in the main urban area of Mudanjiang City based on analytic hierarchy process(AHP) and geographic information system (GIS) spatial analysis. The results show that the suitability of construction land in the main urban area is good, with the suitable and relatively suitable areas accounting for 58.2% of the total area, and the geological environment in the south of the main urban area is the most superior. Thus it is suggested that Mudanjiang City develop moderately to the south, and protect the ecoenvironment and permanent basic farmland.
