农业资源与环境系统优化模式研究——以汉江上游安康地区为例

A STUDY OF THE OPTIMAL PATTERNS OF AGRICULTURAL RESOURCES IN RELATION WITH ENVIRONMENTAL FEATURES ——Taking Ankang region as an example

农业资源与环境是一个相互作用、相互影响的有机系统。安康地区生成农业资源环境的主要特点是：地貌类型多样，以山地为主，山高坡陡，气候条件优越。运用定性与定量相结合的方法，将本区农业资源划分为五大结构类型，据此并遵循功能效益原则，设计出农业资源与环境系统优化的三种模式。

In this paper, agricultural resources and the accompanying environment,influencing and interrelating with each, are regarded as an organic system. The main characteristics of the environment forming the agricultural resources in Ankang Region are as follows: varied types of landform, the predomination of mountainous and hilly areas, mountains relatively high and slopes relatively steep, and the superior climate conditions. The agricultural resources in this region are divided into five structure types through a combination of qualitative and quantitative analyses.Based on this and following the principle of function and benifits,three types of pattern for optimization of the agricultural resources with reference to environment in the region are designed.
