The results showed that during 2000 to 2010, a large number of forest land translated into grassland and cultivated land, resulting in forest area dropped sharply, and the area of cropland and grassland increased; Construction land had a trend of expansion; Water area and unused land area decreased continuously. It was suggested to strictly control the conversion of forest translate into grassland and cultivated land, and to ensure that the forest land isn’t reduced again; Construction land growth should have a clear plan, not only economic development but also to avoid the destruction of the ecological environment; At the same time, It was suggested to protect the waters land to avoid further reduction.
