摘要：金沙江干热河谷区范围包括云南和四川境内的金沙江干流河谷及其支流河谷部分，其面积达150多万hm2。本文通过对干热河谷的演变过程、形成的成因进行了分析，结合干热河谷攀枝花段的特点，认为攀枝花干热河谷的形成是以“焚风效应”的作用为主，人为干扰加速次生植被退化，促使干热河谷的范围扩展；根据干热河谷的特点与生境的退化特点，提出干热河谷生态恢复与重建的对策：一方面，开展森林植被的水分消耗规律和土壤水分供应能力的研究，提出了干热河谷“适度”造林技术设想，即遵循“适地、适树、适结构、适模式”的原则，模拟自然森林植被群落，建立起植被与生境土壤水分条件的群落生态关系，形成稳定的“适度”林分结构(适宜的林分密度和适宜的乔、灌、草配置结构)的造林模式；另一方面，借鉴20世纪90年代以来全球生态重建与经济可持续发展的最新进展、经验与教训，结合该区天然林资源保护工程建设，提出干热河谷森林可持续发展策略，以生态农业、生态林业、生态旅游等生态产业为主的生态经济体系，形成生态型产业结构，倡导区域经济的生态化和经济社会活动的生态化。 关键词：干热河谷；成因；生态恢复与重建；对策；“适度”造林技术；森林可持续发展策略 The formative causes and the

includes the valley part of the mainstream and its tributary of
Jingshajiang River in Yunnan and Sichuan boundary. By analysing the
developing course，the formative cause of dry-hot valley，the dry-hot valley in Panzhihua is affected mainly by
" burning wind effect "，and the disturbance by
human activities to speed up the degeneration of the raw vegetation
and to make the scope of dry hot valley expanding. According to the
characteristic of the dry hot valley and the degeneration features
of its ecological environment，the suggestions of the ecological restoration and
rehibitation in the dry hot valley is as follow：(1) By studying the moisture consumption of forest
vegetation and soil moisture supply ability，the technical tentative idea of " moderate "
afforestation in the dry hot valley is brought up, that is,
following the principle of " suitable species to suitable site,
to suitable stand structural, and to suitable silvicultural pattern
", simulating the natural forest community, the stable
“moderate” stand structure ( appropriate stand density and
appropriate arrangement of tree, shrub and grass ) is set up. (2) By
refering to the newest progress，experience and lesson of
the global ecological reconstruction and the economical sustainable
development since 1990s，the forest sustainable
development strategy in the dry hot valley is put forward， that is, the ecological economic system mainly with
ecological industrial，such as ecological
agriculture，ecological forestry and ecological travel et al.,
should be built, and the ecological type industrial structure,
proposing ecologization of regional economy and economic society
movement, will be formed. Keywords：dry-hot
valley; cause; ecological restoration and rehibitation;
countermeasure; “moderate” afforestation technology; forest
