祁连山东段北坡农业景观带人地交互作用

Study on the Interaction of Agricultural Landscape-belt in the North Slope of Qilian Mountain' s East Segment

祁连山东段北坡地区的自然环境具有突出的多样性、脆弱性和不稳定性特点,并由此形成多样的自然景观带和与之相适应的人地系统。根据气候、地貌等地理要素分异,将研究区分为9个农业景观带。对农业景观带人地交互作用进行了探讨,得出了人口压力下的空间分异模式,并对土地利用程度与效益特征、农业生产经营、耕作制度进行了比较,最后根据研究区人地系统的基本特征,提出了不同景观带间平衡发展的协调对策与整合模式。

The north slope of the Qilian mountain' s east segment is a special region that haves the characteristics of diversity, unstability, regional transition frangibility, and is now being a Man-land system with diversity. Based on the differences of the geographical condition, the paper divides the studied area into nine agricultural landscape-belts. The paper also analysis on the alternated relationship between human and nature in this belt, and sets up a spatial disparting model adapting to the development of population. At the same time, this paper also does some research on the land-use development and its benefit, agriculture production and its managing system, etc., and finally gives some corresponding strategies and the conformity model.
