摘要
土地适宜性评价是土地合理利用的重要依据,可以为土地利用规划提供科学合理的决策辅助.该研究以土地利用规划为背景,以银川市七子连湖湿地区域为研究对象,基于土地利用现状和生态价值量现状等资料,建立了生态价值优先的土地适宜性评价体系,并综合地理信息系统、遥感等学科技术对研究区域内各评价单元分别进行了单因子和多因子综合的评价应用,得到了七子连湖湿地区域的土地适宜开发程度分级量化成果,分为禁止开发区、限制开发区、适度开发区、优先开发区,为后续城市规划中的土地利用和空间配置提供依据.
Abstract
Land suitability evaluation is an important basis for the rational land use, it can provide scientific and rational decision aids for land use planning.Under the background of apphcation of land use planning, with Seven Lake Wetland in Yinchuan City as research object, based on land use status and ecological value, the land suitability evaluation system was established based on priority of ecological value.The single factor and multi factor comprehensive evaluation was carried out on each assessment unit in the study area by using GIS and remote sensing technology, the grading quantitative results of land suitability development degree of Seven Lake Wetland were obtained including prohibited development zone, restricted development zone, moderate development zone and priority development zone, which will provide corresponding reference for future land use and spatial distribution in city planning.
