中文摘要: 为分析榆神府矿区生产对区内水体及湿地的影响,应用3期Spot遥感对比数据,研究了榆神府矿区1990年、2001年、2011年3个时期的水体、湿地分布及其面积动态变化规律,得出:水体面积在研究期内呈现持续下降趋势,19902001年及20012011年的减少率分别为17.73%和22.39%;湿地面积先增大后减小,即19902001年湿地面积增加了65.91%,20012011年,湿地面积减少了50.92%;水体面积在外力驱动下衰减的过程中演替为湿地及其他类型用地,使湿地面积在20 a间基本保持不变;气候变化、煤炭资源开采、生态环境建设和水源地兴建等是水体湿地面积变化的主要驱动因子。通过模糊层次分析法确定了各驱动因子对地表水体湿地面积变化的作用大小(权重)和序关系,分别为煤炭开采0.375,气候因素0.292,水源开采0.208和生态需水0.125;为保护区内水体湿地,推行保水采煤、减少地下水抽采及减少高耗水植被是行之有效的措施。
英文摘要: The distribution and changes of surface water and wetlands at Yushenfu mining area were investigated by using the data sources from three periods Spot remote sensing image,i. e. 1990,2001 and 2011. The results show that: Surface water area was shrunk in these period. The rates of shrink from 1990 to 2001 and from 2001 to 2011 were 17. 73% and 22. 39%, respectively; Wetland area extended 65. 91% from 1990 to 2001,however,decreased by 50. 92% from 2001 to 2011; Surfacewater area changed to wetland or other type of land,which make wetland area maintained unchanged in the past 20 years; It was main driving forces that climate change,coal mining,ecological environment protection and water source construction driven surfacewater and wetland area evolution; The role and order of each driving force factors for surface water and wetland evolution were determined by the fuzzy analytical hierarchy approach, the contributions of the coal mining,climate change, reservoir construction and recovery of vegetation was 0. 375,0. 292,0. 208 and 0. 125, respectively; Coal mining with water protection,groundwater extraction reduced and high water consumption vegetation disappeared can be used to protect the water and wetlands.
