四川省金川县土地利用结构的初步研究

金川县地处青藏高原向横断山脉深切峡谷过渡地带,在土地利用上具有明显的立体结构。森林采伐、土地开垦都在不断改变土地利用的状况。怎样合理利用土地,成为目前突出的问题。本文以1/20万土地利用现状图量算面积及1984年以前的统计资料为基础,着重分析了土地利用结构及其调整问题。

A PRELIMINARY STUDY OF THE STRUCTURE OF LAND USE IN JINCHUAN COUNTY,SICHUAN PROVINCE

Jinchuan County is situated in the transitional rigion between the Qinghai-Xizang plateau and the deep gorges area of the Hengduan Mountains. Here the structure of land utilization is evidently of three dimensions. Destruction of forests and reclamation of waste land have constantly been changing the status of land use. How to use the lands rationally becomes an outstanding problem at the present time. Based on the present land use map on the scale 1:200,000 and the related data before 1984, a preliminary study of the land use structure in the typical region was made. This thesis emphatically analysed the structure of land use and the adjustment of the structure of land use.
