Character of Landscape Structure in the Ecotone between Agriculture and Animal Husbandry in Northern China Using Spot-5 Remote Sensing Data

Limited by the scale,it is difficult to analyse the special village-landscapes using remote sencing images of low spatial resolution .But the high-resolution remote sencing images of such as spot-5,could reflect the spatial information and the relation of size and shape of landscape and the abundant detail information the best. The paper recounts the geometric correction,matching and fusion of 2.5m panchromatic and multi-spectrum data using 1∶10 000 landuse map or relief map and digital elevation model(DEM)in brief.Based on high-resolution remote Sensing image,this paper analyses the different characters of the village-level landscapes structure in different physiognomy positon in big scale in Guyuan count of Hebei province lying in the ecotone between agriculture and animal husbandry in northern China.For the highland topography and the special human activity between agriculture and animal husbandry,the base landscape structure of the study area is crisscross motion between cropland and pastureland that is obviously different with the farming area in north china and the pasturing area in Neimeng.The paper concludes four landscape types: the pastureland being in the ascendant pasture-farm-forest mountanious region landscape in south area,the cropland being in the ascendant farm-pasture hilly region and plain transition landscape in middle area,the cropland being in the ascendant farm-pasture undulant highland landscape in west,and the pastureland being in the ascendant pasture-farm river valley and alluviation plain in north.From the analysis of the landscape structure,the transformation laws because of the interaction of natural and human being should be found in the four village-landscapes.
