      陆表自然资源类型子类型空间分布表征变量表征依据
      土地资源土壤生态地理区生态地理划分区中考虑了全国土壤差异,能反映全国土壤的分异性
      地形（1）生态地理区
      （2）多年NDVI      		（1）生态地理划分区中考虑了大尺度的地形差异
      （2）中小尺度地形形成垂直地带性,影响植被分布,因此NDVI能间接表征中小尺度地形的空间分布特征
      利用方式多年NDVI不同土地利用方式具有不同的植被覆盖度,如裸土、建筑用地、农田、草原和林地等,年均NDVI具有较大的差异,因此NDVI能间接表征土地利用方式的差异
      地表水资源河流多年NDVI对可见光高反射,NDVI为负值,可用NDVI直接表征
      沼泽
      湖泊
      冰川
      永久性积雪
      气候资源大气水（1）生态地理区
      （2）多年NDVI      		（1）生态地理区考虑了降水条件,刻画了大尺度的大气水的空间分异性
      （2）不同大气水条件影响自然植被类型,形成如森林、草原和荒漠等差别,影响人工栽培植被的作物类型、熟制等,均在年均NDVI上有差异,因此多年NDVI能够间接表征大气水的空间分布特征
      光能和热能（1）生态地理区
      （2）多年NDVI      		（1）生态地理区考虑了光能和热能条件,刻画了大尺度的光能和热能的空间分异性
      （2）不同的光能热能影响自然植被与人工植被类型,在年均NDVI上有差异,因此可以用多年NDVI间接表征光能和热能的空间分布
      风能生态地理区生态地理区包含温度带和地形地貌,能过表征风能资源的空间分异
      生物资源（植物）森林（1）生态地理区
      （2）多年NDVI      		（1）生态地理区划分反映了植被差异
      （2）植被覆盖度越大,NDVI值越高;多年NVDI能直接表征森林空间分布特征
      草场（1）生态地理区
      （2）多年NDVI      		（1）生态地理区划分反映了植被差异
      （2）植被覆盖度越大,V值越高;多年NVDI能直接表征草场空间分布特征
      作物（1）生态地理区
      （2）多年NDVI      		（1）生态地理区划分反映了植被差异
      （2）植被覆盖度越大,NDVI值越高;多年NVDI能直接表征作物空间分布特征
      荒漠（1）生态地理区
      （2）多年NDVI      		（1）生态地理区划分了不同的荒漠区
      （2）植被覆盖度越低,NDVI值越低;多年NVDI能直接表征荒漠空间分布特征
