【摘要】 掌握矿区土地利用动态变化规律对矿区的总体开发有重要意义。论文将地理信息系统(GIS)和遥感(RS)作为技术手段应用到矿区土地利用动态变化研究中,主要内容包括: ① 开采沉陷是矿区土地利用动态变化的主导因素,采用概率积分法对开采沉陷进行预测。 ② 将预测结果导入GIS软件Arcview中,分析开采沉陷对各类型土地资源的影响程度与位置。 ③ 利用ENVI对遥感影像进行处理,利用遥感资料调查研究区内的植被状况,土地利用现状,并根据遥感资料对原始数据库进行更新。结合GIS与RS对研究区进行土壤侵蚀状况评估。 ④ 根据GIS空间分析的结果,预测与评价不同时期研究区内各类型土地资源的变化情况,并以专题地图的形式将研究区内的土地利用动态变化情况表示出来。更多还原

【Abstract】 Mining subsidence is the dominating cause of dynamic change in mining area. It is significant for the exploitation in mining area to predominate its rule of land use dynamic change. GIS and RS are used as technical means into the study on land use dynamic change in mining area.Probability integral method is used to forecast the mining subsidence of the specific pit mining play.The forecasted results are brought into Arcview, and the influencing degree and position because of mining subsidence on all kinds of lands are analyzed.The RS image processing is completed by ENVI. The vegetation and the present situation of land use in study area is investigated using RS. The old database is updated based on RS. The soil erosion in study area is evaluated using GIS and RS.Based on the results of spatial analyze, the change of all kinds of lands in different periods is forecasted and assessed. The change of dynamic land use in study area is showed by the matic map.更多还原
