  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
  2. But now it ' s urgent to adopt new methods for calculating the head loss of regional drainage due to some factors such as long length, large flow quantity and probable strong topographic change

  6. Nondimensional distribution index was able to describe the spatial pattern of each landscape patch type and indicate the affection of the topography on the change of the pattern. for excluding the disturbance of the area, distribution index can describe the difference between the actual distribution and the standard distribution of each patch type on the topographic gradient. and according to this, kinds of comparative analyses were availed

    運用地形分佈指數克服了不同地形因子各梯度內面積的差異，同時也消除了各景觀斑塊類型的面積比重差異，能夠準確地反映不同景觀斑塊類型在一定的地形因子梯度上的實際分佈情況與標準分佈的偏差，使分析不受面積的影響，其結果具有較好的可比性和可解釋性；且通過對優勢分佈范圍、分佈趨勢線特徵的分析，能夠獲得森林景觀空間分佈格局及其變化的多種信息。
