Basing on the sketch date of land use in the year of 2000,using the more explicit landscape metrics we quantify and analyze the landscape spatial pattern in Horqin sandy land and in term of regions and banners to reflect the affect of landscape pattern on regional eco-environmental.The result shows:(1)Grassland landscape is the biggest in area,the most extensive in distribution,and the strongest in consecution substrate landscape in Horqin sandy land.Its area proportion is 47.6%,patch number proportion 29.8%,average patch area higher than 3.25 km2/per,patch dispersion index only 0.40.The area proportion of farmland and woodland is also great by 26.3% and 10.2%.The area proportion of mobile sandland which is 5.8% and alkaline land which is 3.1% is small.(2)The Banners,counties on the alluvial plain on both side of the downstream and bayou of western Liaohe River.The landscape pattern on the regional reflects the feature of mosaic of substrate landscapes of farmland,mobile sandland and grassland.(3)The correlation analysis shows,there is a remarkable positive correlation between the eco-environmental index and the average patch area of the landscape,and that there is a negative correlation between the fragmentation index of landscape and the eco-environmental index.
