Abstract 铁凤山区是川东平行岭谷区的一个组成部分。本文仅取一段作为研究区(图1),位于108°03′50″—108°19′15″E,30°46′35″—30°58′16″N,地跨四川万县和开县两县,土地面积约325.6平方公里。
使用网格法的具体步骤:1.通过1986年野外实地调查,了解研究区的自然环境和社会经济条件,并在室内遥感资料的判读的基础上,编制了当地1:10万土地利用现状图;2.在包含研究区的范围的1:10万地形图上,取方格边长为0.4厘米,按格将全区分割成2035个方格;3.逐格提取全区的高度(即海拔)分级数据,坡度数据和土地利用类型资料,并分别加以整理、制图;4.对地形因子(高度、坡度)、土地利用在区内的分布特征及彼此间的关系进行全面评价、分析。
Other Abstract Tiefeng Mountainous Region belongs to mountain and valley paralleled region in East Sichuan. The study region, with the total area of 326km2, is a part of this region which is situated in 108°01’——108°19’ E and 30°47’- 30°58’N. Wanxian County and Kaixian County of Sichuan Province meet here.The study region is at 170--1300m above sea level. The most of its land is consists of low-mountain and hill, Tiefeng Mountains range from NE to SW. This study region belongs to subtropical monsoon zone. There is an obvious vertical difference of climate in it.There are 6 land use types in the study region.They are forest iand, sparse-wood land, bus bland, water body, paddy-field and dry farmland.Based on collection and classification from the grid data of the study regi- on, compiled are 3 grid maps. They are the classification map of altitude, the classification map of slope and the classification map of land-use types. The research results state clearly the close relationships between the land-use characteristics and the geomorphologic factors (altitude, slope and so on).For example, the area of the forest land shows increase trend with the increasing of altitude and the decreasing of slope. The case of sparse-wood land proves the quite contrary. As to the bushland, dry farmland and paddy-field, all of their area show increase trend with the increasing of altitude and slope.The analysing results indicate that the land use of the study region is to a great extent increasonable. The problem mainly includes the rather high rate of cultivated land(206km2), the rather low rate of forest cover(10%), and the extremely large sparse-wood land and bushland(83km2). Therefore, it will be necessary to decrease properly the rate of cultivated land in the region, to enlarge the forest cover rate in it. Especially, all the slopeland of >25° should be returned to forest and grassland.
