  1. 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
