The Method Study of Spatial heterogeneity evaluation on the Landscape Pattern Of Farmland Shelterbelt Network

Abstract: In order to measure the spatial heterogeneity of shelterbelt networks on landscape scale, the distance coefficients of the reasonable and existent landscape indexes of the farmland shelterbelt networks are compared and analyzed on the basis of landscape ecology, combining the spot5 high resolution satellite imagery with GIS .On the basis, the methods are advanced to evaluate comprehensively the spatial heterogeneity through the spatialization of the evaluation indicators, so as to show the spatial differentiation of shelterbelts distribution. The methods resolve the disadvantages of lacking spatiality of overall evaluation, and make the evaluating results have more directive significances for shelterbelt management. With the methods, the spatial heterogeneity of shelterbelt network was measured and evaluated in the Midwest of Jilin province. The results show that the spatial landscape pattern of the farmland shelterbelt networks is not reasonable in the region. The region of acute shortage area account for 42.95%, but few regions have reasonable pattern of shelterbelts. Therefore, it is necessary to make strenuous efforts to construct the farmland shelterbelt networks in the study area.
