摘要
山地自然环境的带层性差异奠定了孕育农业资源的异质性基础 ,从而决定了山地农业资源利用的地域特殊性及其开发利用的模式多样性。本文以陕西秦巴山地为例 ,从分析土地类型地带性分异规律入手 ,揭示了山地农业资源生成、演化及其分异的时空规律 ,据此并依据生态经济学原理和可持续发展准则 ,提出陕西秦巴山地农业资源优化利用的空间层次模式和产业经营模式。
The optimal use of agricultural resources concerns the sustainable ecological,economic and social development in mountainous area. Especially,there are a lot of problems in mountainous region,such as vulnerability of eco environment and severity of man induced problems.Thus,it is of important theoretical significance and practical value to the use of optimal models of the agricultural resources in the mountain region on the basis of system analysis of mountain agricultural resources structure and its spatial patterns with district distribution principle of mountainous area,taking landscape ecologic theory and sustainable development norms as the guides. Structural patterns of mountain ecological types are regarded to be related with quality,quantity and spatial composition of land types in concerned area.Analysis of the structural pattern can facilitate the revealing of the heterogeneity and order laws of form and distribution of agricultural resources.Thus,the theoretical principles are identified to help understand ecological characteristics and suitable way of use agricultural resources so as to conduct scientifically the practice of model design of sustainable agricultural resources use.In this paper,taking Qinling Daba mountain region as an example,based on the systematic analysis of spatial,quantitative and qualitative structure of eco environmental pattern,two optimal models such as spatial hierarchic model and industrial ones for agricultural resources use in mountain system in the study area have been put forward.
