运用“3S”技术对驻马店市土地生态环境现状及土地生态敏感因子进行了调查,得出了土地生态敏感因子单要素图;采用GIS空间分析技术得到了土地敏感性分区图,指明了各土地生态敏感区的土地利用方向,为驻马店土地利用分区提供了科学依据。研究表明:驻马店市有2个高度敏感区,4个中度敏感区,2个一般敏感区,2个生态敞开区;另外,几乎每个区的主导因子都不同,即每个区的重点土地生态环境问题不同,应该分别对待。
Investigation was made of the current land ecological environment and land ecological sensitive factors in Zhumadian, Based on the 3S technology, a single-factor map was plotted out, By means of the spatial analysis technology of GIS, zoning of land sensitivity was also conducted, providing scientific basis for zoning of the land of Zhumadian for land use,
