通过对东北西部（主要是吉林省西部）和内蒙古东部地区环境变迁的实地调查和实地考察，分析了我国干旱化和生态环境变迁的现状。探讨了人类活动在干旱化中的作用及其对中国社会经济的影响。本文就一系列问题提出了我们的思考，包括：1）中国北方干旱化形势严峻，生态环境总体状况持续恶化; 2）人类不合理活动对生态环境的影响是加速干旱化的重要因素; 3）由于这两个特点：半干旱区作为气候生态的过渡带，其敏感性和恢复能力是干旱化研究的重点地区之一;（4）当前人类退耕还林还草活动必须遵循自然规律，在规划一个绿色山清水秀的美丽远景地方面;（5）有序的人类活动是改善生态环境的根本对策。缓解北方干旱化的负面影响，实现可持续发展;（6）政府通过有序的人类活动进行生态治理的政策与现行的以家庭为单位的农业生产定额制度存在一定的冲突;（7）必须认真考虑生态环境治理中的投资、经营和回报之间的关系。
Based on our surveys and site investigations on environmental changes in the western area of Northeast China (mainly the western area of jilin province) and the eastern area of Inner Mongolia, the present statue was analyzed of aridification and life-supporting environment changes of China. The functions of human activities on aridification and the social and economic impacts on China were also explored. In this paper, we offered our considerations on a set of issues, including: 1) The aridification in the northern China is in severe situation, and the general conditions of eco-environment in such a region continue to deteriorate; 2) The influence of irrational human activities on eco-environment is a vital factor to speed up aridification; 3) Because of the two features: its sensitivity and its ability to recover from a bias process, the semi-arid area, characterized as the climatic and ecological transitional zone, is one of the key areas for aridification researches; 4) The natural rules must be followed in present human activities to convert land for forestry and pasture, and in the planning for a perspective beautiful land with green mountains and clean rivers; 5) Orderly human activity is the radical countermeasure to improve eco-environmental conditions so as to alleviate the negative impacts of the aridification in the northern China and to realize sustainable development; 6) The government policies of eco-treatment through orderly human activity conflict, to some extent, the current system of fixing farm output quotas on the household basis; 7) The relations among investments, operations and rewards in eco-environment treatment must be carefully considered.
