Analysis Of The Landscape Pattern In The Saihanwula Nature Reserve

The study was based on the software of ENVI4.2, Arcview GIS3.2 and Arc Info to analyze the date of satellite remote sensing of TM , geological map and DEM data of Balin Right county in 2007 and field investigations in August .2008~2009 at Saihanwula nature reserve area , Chifeng City, Inner Mongolia that classified the landscape type and definite the hypostasis of landscape with slope, aspect and elevation etc. The result showed that: 1.There were 12 main landscape types in this study area .They were the Mountain Forest, the Mountain Steppe, the Mountain Shrubby, the Mountain Meadow, the Valley Wetlands, the Sandy Grassland, the Sandy Shrub, the Farmland, the Mountain flowstone beach, the Plantation, the ancient city of Liao dynasty, and the Reservoirs.2.In this study area, the Mountain Forest was the biggest in the landscape area, the dominance, the shape index, the abundance and the edge density .The artificial landscape was more regular than other nature landscape and there was no serious fragmentation in all type of landscape.3.In this study area,, the diversity index was 1.771 and it was not very high. The evenness index was 0.712 and it was in middle range. The dominance index was 0.714 and it was high. The fragmentation index and deviation index were low, respectively 0.007 and 0.068.4.The Mountain Forest was mainly distributed in the slope and the half shaded halves of gentle slope and the shaded halves at the altitude of 1200~1600m.The Mountain Grassland mainly distributed in the gentle slope and semi-sun side of exposed halves at the altitude of 800~1200m. The Mountain Shrubby mainly distributed in the shaded halves of gentle slope and the half shaded halves at the altitude of 1000~1200m. The Mountain Meadow mainly distributed in the gentle slope and the exposed halves of slope above the altitude of 1800m. The Valley Wetlands were mainly distributed in the flat slope, gentle slope and the exposed halves of slope at the altitude of 800~1200m. The Sandy land mainly distributed in flat slope and gentle slope at the altitude of 800 ~ 1200m. The Farmland mainly distributed above the sea level of 800-1200m′s flat slope. The Mountain flowstone beach mainly distributed above the altitude of 1600m of steep slopes, rapid slope of the shaded halves , and the half shaded halves.
