【摘要】 利用1994年和2006年的Landsat TM遥感资料解译仙女湖景区开发前后生态环境质量的变化情况,分析结果表明:仙女湖风景区自开发以来比较注重生态环境的保护,景区林地中度和中高度覆盖度面积呈上升趋势;仙女湖风景区内土地利用类型的变化主要体现在农田和建筑用地面积上,即农田面积减少了7.52km2,占总面积的3.74%,建筑用地面积增加了6.2km2,占总面积的3.09%;根据2006年的卫星资料,仙女湖风景区土壤侵蚀强度以微度和轻度为主,占总面积的98.27%,中度侵蚀主要集中在坡度较大、植被覆盖较低的山区。更多还原

【Abstract】 By means of Landsat TM remote sensing data in 1994 and 2006,the change of environmental quality in Fairy Lake resort was analysed before and after exploitation.The results showed that:its ecological and environmental protection had been paid more attention since the scenic area was exploited,and medium and high coverage area of scenic woodland showed an upward trend;the land use within the scenic area changed mainly in agricultural and construction land,which agricultural land decreased 7.52 km2,account for 3.74%,and construction area increased 6.2 km2,account for 3.09%;according to satellite data in 2006,the scenic degrees of soil erosion intensity were mainly micro and light,account for 98.27%,and moderate erosion was mainly concentrated in steep mountains with lower vegetation coverage.更多还原
