长江三峡地区山地资源的分层结构特征

HORIZONTAL DISPOSITION AND EXPLOITATION OF THE MOUNTAIN RESOURCE IN THE REGION ALONG THE THREE GORGE REACHES OF THE CHANGJIANG RIVER

长江三峡地区中低山地存在多级不同性质类型的地貌面，与此同时，在垂直方向上分层的水、热资源配置又明显优于中国东部相应纬度水平地带的水、热资源配置。因此，本文强调在该地区低位地貌面开发过度情况下，中、高位地貌面的经济开发，旅游开发与农、林、牧开发相结合。

There are the multilayered landform surfaces with different morphogenetic features in the mountainous region along the Three-Gorge reaches of the Changjiang River, including the peak plain (the summit level), the step-and-platform topography (the piedmont flats) and the river terraces. Besides, the vertical disposition of temperature stratification and atmospheric water in the mountainous region is superior to the horizontal disposition of those in the eastern China, therefore, it is emphasiazed in this paper to exploit the middle-high landform surfaces, in the way of tourism, agriculture, forestry and animal husbandry, since the lower landform surface has been exploited excessively.
