| 摘 要： | 选取黄土高原的典型区域--陕北作为监测区域,以MODIS和TM资料作为主要数据源,从可业务化的角度采用植被指数法进行了植被覆盖率的遥感反演,对4种生态气候区植被覆盖率季相变化特征进行了分析,并对陕北生态环境治理前后植被覆盖率的变化进行了对比,结果表明:生态治理后陕北黄土高原的植被覆盖率绝大多数地区都是正增长,各生态气候区植被覆盖状况都有了不同程度的改善,生态治理效果最明显的区域在陕北南部.

| Abstract: | The loess plateau of Nortern Shaanxi is chosen as the typical monitoring area. Based on the work of the routine operation of the vegetation fraction by MODIS and TM data the seasonal dynamical change characteristic of four ecological climate regions is analyzed, The data of the environmental reclamation is contrasted. The results show that almost all area Of the Northern Shaanxi have a vegetation fraction increase and each environment is improved in some degree. The Southern Shaanxi has the most obvious effect in the ecological reclamation. |
