- Abstract:
- Landscape ecology evaluation had important significance to regionalization.Maorshan farmland of Heilongjiang Province was taken as example,based on GIS techniques,the data of forest distribution map of 2006,Landsat TM images,topographic map,the second survey data and others were used in this paper.Seven indices such as landscape type,landscape shape index,soil erosion type,terrain factor (slope),land use type,vegetation cover index and weather factor (rainfall) were selected in this model.On this basis,the integrated landscape ecology evaluation was made in the study area,according to the results of integrated landscape ecology evaluation,the landscape ecology planning was finished.The results showed that: the index of integrated landscape ecology was analyzed and reclassified,the landscape ecology planning was made,there were Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ grade regions,which mean better,good,medium,bad and worse; the area proportion sequence of different integrated landscape ecology evaluation region was Ⅱ>Ⅲ>Ⅳ>Ⅰ>Ⅴ,the area proportion of Ⅱgrade region was the largest of the study area,the region eco-environment quality was good.The vertical differences of eco-environment quality were evident,the region eco-environment quality of first and second elevation level was good,the area proportion of Ⅱ grade region was lager of this region,which was largest in second elevation level,the region eco-environment quality of the third,fourth and fifth elevation level was bad.It was very clear that the result of DEM combined to integrated landscape ecology evaluation could reveal the spatial distribution characteristics of landscape ecological quality.
