生态用地空间演变分析是区域生态用地的合理配置、各类用地均衡发展的重要依据。在GIS、ENVI等技术支持下,以长株潭核心区2005、2010和2014年3期遥感数据为基础,结合相关软件进行图像及数据的处理,运用土地利用转移矩阵对研究区生态用地的空间演变进行分析。结果表明:不同时期各土地利用类型的变化有明显差异;耕地转变为建设用地是土地利用变化的主要特征。该研究可为区域土地利用动态变化及监测提供数据支撑,为土地利用规划管理者提供依据,从而进行科学合理规划建设。
The analysis of spatial evolution of ecological land use is an important basis for the rational allocation of regional ecological land and the balanced development of various types of land use. Based on the remote sensing data of CZT core areas in 2005, 2010 and 2014 with the support of GIS, ENVI and other related software, the image and data were processed. Using the land use transfer matrix, Evolutionary analysis. The results show that there are obvious differences in the types of land use in different periods. The conversion of cultivated land to construction land is the main characteristic of land use change. This study can provide the data support for the dynamic change and monitoring of land use in the region and provide the basis for the land use plan managers so as to carry out scientific and reasonable planning and construction.
