河西地区土地生产潜力及人口承载力研究——以张掖市甘州区为例

Hexi area land productive potential and population supporting capacity research——A case study in Ganzhou area , Zhangye city

河西地区是我国生态环境比较脆弱的地区,也是我国人口、资源、环境矛盾最集中的地方,由于长期对土地的不合理利用加剧了这一矛盾的激化。如何合理利用土地资源成为首先要解决的问题。文章以甘州区为例,来探讨该区土地潜力,通过应用生产潜力模型,并结合统计资料,建立了绿洲农区土地潜力评价系统和指标体系,通过应用气候(光温水)生产潜力模型和气候-土壤生产潜力(自然生产潜力)对该区的土地生产潜力进行评价。希望研究对于绿洲农区合理、有效、可持续的利用土地资源,使其最大程度的发挥土地生产潜力具有意义。

HeXi area is comparatively fragile area of our country ecological environment, this one intensification of contradictions being also our country population , resource , all together environment contradiction place , making use of having aggravated since the long range is unreasonable to land. How rationally make use of land resources to become the problem needing to solve first. The article has taken Gan State area as example , has come to discuss that area land potential , to pass the implement applying GIS, and to be tied in wedlock a statistical data , has built the oasis agriculture District land potential carrying out valuation on to owing the area land a latent productive capacity appraising system and index system , applying the climate （glorify warm water） latent productive capacity model and the climate soil latent productive capacity （natural latent productive capacity）. Land resources studying to rational , effective , sustainable oasis agriculture District making use of, messenger it＇s maximal degree＇s brings the land latent productive capacity into play , has guiding significance.
