In this paper, based on land use maps of 1976, 1988, 2003, which were interpreted from the landsat mss / tm / etm imageries, and the map of main road, with the buffer analysis tool in arcgis 8, we studied the land use and land cover change on the two sides of the main roads in xishuangbanna, then we studied the impact of population density and the topographic factor on road effects. during the study both the comprehensive land use dynamic degree model and the land use degree comprehensive index model are taken into account, we put forward a compensatory model ? “ amendatory comprehensive land use dynamic degree model ”
由於人類活動干擾強度加大，公路效應深度不斷擴展， 1976年為5km ， 1988年為7km ， 2003年達到11km ;受自然、社會條件的影響，不同路段的公路效應存在較大差異，甚至同一路段兩側效應也各不相同。 1976年至2003年，距公路不同距離范圍內的人口密度都在增加，且距離公路越近，人口數量密度越大、增長越快，人口分布有向公路兩側聚集的趨勢。選取人口密度為大、中、小三個樣區分別分析公路效應的范圍表明，人口密度 -
Employing the satellite images of landsat - mss and landsat - tm and the integrated techniques of rs, gis, and gps, the authors, with maotiaohe river basin as a case, studied the process and driving factors of land use / cover changes since the beginning of 1970s, and modeled the possible land use / cover changes scenarios in the coming 10 years based on clue - s model, and then made an ecological evaluation on effect of the changes over the past 30 yeas as well as in the coming 10 years by using theory and method of landscape ecology. in this research, the authors, from the angle of international lucc studies, threw much light on the land use / cover changes in the basin and also the derived ecological and environmental problems such as karst rocky desertification
本文以位於貴州中部的貓跳河喀斯特流域為對象，以1973年的mss和1990年、 2002年的tm等衛星影像為數據源，運用rs - gis - gps集成技術，研究了該地區在過去三十年間土地利用/覆被變化的過程、驅動機制，運用clue - s模型模擬、預測了該流域在不同目標情景模式下的土地利用/覆被變化，並運用景觀生態學的方法對貓跳河流域過去三十年間的土地利用/覆被變化以及未來不同情景模式下的土地利用/覆被變化的生態效應進行了評價。 -
The northern part of ailao mountain, located in the middle of yunnan province, was selected as study area. based on three landsat mss / tm / etm satellite images, as well as “ 3s ” technology combining with the method of mathematical statistics, the objective of this paper was to analyze the law of spatial ( gradient, slope orientation and elevation ) and temporal changes in land use / land cover on the northern part in the periods of 1974 1987 and 1987 2003. and analyzes land use / land cover change character in nature reserve and its meighbour region within the confine of the study area
本文選擇滇中哀牢山北段作為研究區域，以1974年mss影像， 1987年tm影像和2003年etm影像為主要數據源，運用「 3s 」技術，並結合統計分析，探討研究區1974 1987年、 1987 2003年間土地利用的時間和空間（坡度、坡向、海拔）變化規律，並分析了研究區內的自然保護區及其周邊土地利用/覆蓋變化特徵，以期為山地土地資源的可持續利用和生態保護等方面提供依據。
