摘要
基于GIS空间分析技术,选择对土地利用生态敏感性影响较大的评价因素,采用多因素加权叠加法,对龙岩市的土地利用生态敏感性进行深入分析。按生态敏感度的高低将研究区划分为极度敏感区、高度敏感区、敏感区、不敏感区和很不敏感区5个不同类型区域,并提出了土地利用的建议,为研究区的土地利用总体规划提供参考信息。研究结果表明,龙岩市土地利用敏感区、高度敏感区和极敏感区面积共占全市的的53.56%,说明龙岩市土地利用生态敏感性较高,应对全市作合理的主体功能区划。
The assessment of sensitivity of land use eco-environment is the base of the land use planning. With the help of ArcGIS spatial analysis, and by using the multi-factor weighted overlay method, the study area has been divided into five different type regions （the extreme sensitive area, the highly sensitive area, the sensitive area, the insensitive area and the very insensitive area） . The results show that： about 53.56% of the study area was lower moderate eco-environment suitability for land use, which also showed that the eco-suitability of Longyan City was rather low, thus providing scientific foundation for rational land use distribution and regional eco-envi- ronment protection in the future.
