摘要: 本文讨论了横断山地区的垂直自然带和农业的垂直分布。指出:横断山地区是一个复杂的生态系统,其垂直自然带是农业垂直分布的自然基础。认为本区农业应开展多种经营,建立以林为主的山区农业垂直系统。

Abstract: The Hengduan Mountain region(HMR)is a transitional zone from the Qinghai-Xizang Plateau to the Yunnan-Guizhou Plateau and Sichuan Basin,with mountains and deep gorges running in parallel from north to south,The vertical zonation here is very conspicuous,and the agricultural development in various altitudinal zones is very different, Vertical zonation,agricultural distribution(including plantation,forestry and animal husbandty)are discussed in the paper,The complex regional differentiation is correlated with the geographical location,and absolute and relative altitudes, From southeastern and southwestern margins to the interior,with increasing altitude,in addition to the differences of the basal belt,there is a decrease in number of vertical zones and simplification of spectra,The regional differentiation of upper forests limits and the dry valleys are discussed, It is considered that HMR is a complex ecosystem,in which the vertical zonation is a natural base of vertical distribution of agriculture,The exploitation and utilization of natural resources should be paid attention to,After discussing present agricultural situation,it is pointed out thai diversified economy development should be emphasized and taken as a fundamental policy;the mountain agto-ecosystem with forests as main parts should be established;the existing farm land should be fully utilized so as to increase per unit yield;economic forests and fruit trees should be vigorously developed;contradiction between plantation and animal husbandry should be well coordinated;and plantation,forestry and animal husbandry should be well developed together,So far as this,special farming system in HMR could be established.
