福建地貌基本特征与农业生产的关系

本文首先从发展农业生产角度出发,分析了福建地貌的基本特征及其对农业生产的直接和间接影响。继而论述了地貌与农业自然灾害的关系,指出了坡度陡、降水强度大和黑云母花岗岩分布三者相结合的部位是农业生态脆弱的地段。最后,根据福建山河分布格局,提出改善福建农业生态的根本性措施——建立防护林体系。

THE RELATION BETWEEN BASIC GEOMORPHIC CHARACTERS AND AGRICULTURAL PRODUCTION IN FUJIAN

In this paper, according to the development of agricultural production, five basic geo-morphic characters in Fujian are given. Direct and indirect effects of these characters on ag-ricultural production are analysed. Then, this paper discusses the relation between geomor-phology and agricultural natural hazard and points out that there is a close relationship bet-ween geomorphology and natural hazard such as flood, typhoon, soil and water erosion, hill-slopes slip, and mud-rock flow. This paper suggests that the region with steep slope, heavy rainfall, and black mica granite is the weak agricultural ecological region in Fujian. Final-ly, according to the distribution of mountains and rivers, this paper suggests the method to improve the agricultural ecological environment in Fujian is to establish a shelter forest system in the whole province.
