摘要
本文以土地资源结构理论为依据,论述了甘肃省河西走廊地区的农业分区,土地资源质量数量结构、农林牧合理用地构成及区域开发的整体布局。
Starting from analyses of composition and distribution of land resour-
ces, the paper discusses rational arrangement of different land use types.
Hexi Corridor of Gansu Province has been taken as an example, where is
divided into 3 subdivitions: Wuwei temperate steppe desert, Zhangye---
Jiuquan temperate desert and Dunhuang---Anxi warm temperate desert.
Based on quantitative and qualitative features of the land resources and
their suitabilities for agriculture, forestry and livestocking, the rational
distribution of land in Hexi Corridor has been determined, that is, 11.05%
of the whole area is suitable for agriculture, 14.19% for forest and shrub,
26.43% for grazing land,and the water surfaces occupy 0.04% of the whole
land. The author also proposes suggestions with the view to vertical
distribution of mountain agriculture and the establishment of 'San Bei'
shelter--forests.
