- 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
本文选择滇中哀牢山北段作为研究区域,以1974年mss影像, 1987年tm影像和2003年etm影像为主要数据源,运用“ 3s ”技术,并结合统计分析,探讨研究区1974 1987年、 1987 2003年间土地利用的时间和空间(坡度、坡向、海拔)变化规律,并分析了研究区内的自然保护区及其周边土地利用/覆盖变化特征,以期为山地土地资源的可持续利用和生态保护等方面提供依据。 - 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 ”
由于人类活动干扰强度加大,公路效应深度不断扩展, 1976年为5km , 1988年为7km , 2003年达到11km ;受自然、社会条件的影响,不同路段的公路效应存在较大差异,甚至同一路段两侧效应也各不相同。 1976年至2003年,距公路不同距离范围内的人口密度都在增加,且距离公路越近,人口数量密度越大、增长越快,人口分布有向公路两侧聚集的趋势。选取人口密度为大、中、小三个样区分别分析公路效应的范围表明,人口密度
