长江滩地资源调查与开发研究

STUDY ON PHYSICAL,REGIONALIZATION IN THE MIDDLE CHINA REGION BASED ON THE INTERPRETATION OF PHYSICAL LANDSCAPES ON REMOTELY SENSED IMAGERY

利用先进的遥感技术对滩地资源进行调查，可以直接准确地圈定滩地的范围及其土壤性质。本文以遥感技术为基础提出了长江难地的综合开发模式。

Based on an interpretation of the physical landscape types on Landsat images in the study area and their mapping,the qualitative and quantitative analysis of the spatial distribution patterns of the physical landscape types,as well as a combination of the merging of physical landscape types from below to above with the partition of the region from above to below the study area was divided into 5 natural regions, 19 natural sub_regions and 30 small natural regions. The study has shown that(1)it is feasible and reasonable to carry out physical regionalization based on physical landscape types;(2)it is advisable in the regional ization to make a combiation of the merging of physical landscape types from below to above with the partition of the region from above to below;and(3)it is helpful to the improvement of the scientific level and accuracy of physical regionalization to make a combination of qualitative analysis with quantitative one.
