摘要
基于1987、1994和2000年三期TM遥感图像,将徐州矿区土地利用类型划分为建成区、耕地、林地、水体、塌陷地和其他土地等6类,编制了3个不同时段的土地利用结构变化图;提取并分析了土地利用结构转移变化的矩阵信息和土地利用结构的动态变化。研究表明:采煤塌陷土地面积在不断扩大,年均增加率为6.33%,塌陷地复垦速度仍赶不上塌陷速度。着眼于技术、规划、资金和管理等方面的综合视角,探明塌陷土地复垦的工程技术措施和对策,对于进一步加大土地复垦力度,促进矿区土地资源可持续利用,具有重要的现实意义和价值。
With the use of TM imageries of Xuzhou in 1987, 1994 and 2000, the change maps of land use structure of relevant periods of its coal mining areas were compiled, and the classified land use type was divided into 6 kinds, i.e. the construction area, cultivated land, forestland, body of water, subsided land from coal mine and the other land. The situations of dynamic change of land use were analyzed comprehensively, the conversion matrix of land use structure about the different temporal classified TM imageries was interpreted, and the reclamation measures of subsided land were probed. The results indicate that: the area of subsided land due to coal mining was increasing and the speed of land reclamation did not catch up with that of land subsidence. Therefore, it is necessary to accelerate the force to the land reclamation. And from the view of technique, planning, fund and management, it is necessary to adopt the reclamation measures of subsided land, including mainly: (1) to adopt the suitable reclamation techniques; (2) to put forward a general scientific planning on subsided land reclamation of; (3) to construct an effective input mechanism of the reclamation of subsided land; (4) to establish a comprehensive organization to actualize the project of subsided land reclamation.
