- Abstract:
- It would help to predict the influence of globe change to maintain terrestrial ecosystem that research the feedback of land use/land cover(LULC) on climate.We had a study on the spatial pattern of LULC under the local climatic conditions using Landsat ETM+ image,land use map,topographic map,and the spatial distribution data of temperature,precipitation,accumulated temperature by climatic zoning,overlay analysis.The results indicated that:(1) The area percentages of cultivated land,garden,forest land,settlement,industrial land,water bodies and unused land are 54.7%,29.0%,1.7%,7.7%,0.8%,4.3% and 2.1%,respectively.(2) Land use showed obviously spatial distribution laws under the local climatic conditions that the percentage of forest land increases but others decrease with the raising of temperature and accumulated temperature.However,the spatial distribution pattern of forest land is in a reverse manner as well as other land use types with the precipitation growth.(3) The land-use structure of different climate in Liling showed that the spatial of climatic factors formed a relatively suitable area for human beings,which has fertile soil,convenience traffic,high density population and tensely activity.This area is the major area for agricultural production; however,it suffered serious problems from enlarged city and industrial pollution.To obtain sustainable development on social,economy and environment,the local land-use planning must pay attention to the non-agricultural construction occupying arable land,farmland protection and environmental management.
