【摘要】 以兖州南屯煤矿区为例,以四个时期的遥感数据作为数据源,利用GIS的空间分析方法,提取分析了煤矿区30年来土地变化的信息,研究结果显示,从1978年到2007年,矿区耕地减少44%,大部分转化为建设用地、塌陷地、林地。建设用地增加117%,林地增加323%,塌陷地从无到有,到2007年已经占矿区总面积的14%,研究成果为矿区土地利用规划提供了依据。更多还原

【Abstract】 Taking Nantun coal mining area in Yanzhou,Shandong province as an example,the information of change of land use in the mining area over the past 30 years was extracted based on remote sensing data of four periods with GIS spatial analyze method.The results of study showed that in the coal mining area the cultivated land has been reduced by 44% from 1978 to 2007,the reason is the transformation of large areas from cultivated land to construction land,subsidence area and woodland.The area of construction land has been increased by 117%,the area of woodland has been increased by 323%,and the area of subsidence has occupied 14% of the studied area in 2007.The results of study provided a basis for the use planning of land in the coal mining area.更多还原
