克州退耕还林工作的现状、问题及对策

干旱区的生态环境，特别是绿洲的开发，改变了地-气系统的能量交换。几年来对绿洲气候的研究、气候资料的分析和实地考察表明，新疆南部干旱区最近几年的戈壁绿洲开发已改变了整个地州的气候变化，使其变为有利于人类的生存和发展。在戈壁绿洲的开发利用与环境变化之间，存在着2种截然相反的反馈作用：环境变好→绿洲发展→环境更好→绿洲再发展；环境恶化→绿洲退化→环境更坏→绿洲再退化，甚至消失。决定这2种反馈作用的是大环境的变迁和绿洲开发利用中是否合理利用资源和按自然规律办事。本文针对此问题进行了论述。

The Status Quo, Problems and Solutions of The Work of Returning Farmland to Forests in Keailesukeerkezi Autonomous Prefecture

Tire ecological environment in arid areas, in particular the development of Oasis had changed the system of earth - gas en- ergy exchange. Over the past few years, research of the oasis climate, analysis of weather data and field studies showed that in recent years in southem Xinjiang＇ s Gobi, Oasis development had changed the whole state of climate change, to make it conducive mankind＇ s survival and development. Between the development of gobi and oasis and environmental change, there are two diametrically opposed feedback： environment friendly - Oasis development - a better environment - further development of the Oasis, environmental degradation - degradation of the oasis - even worse - a further degradation of the Oasis. 2 kind of feedback that this decision is that the role of big changes in the environment and the development and utilization of Oasis is the rational use of resources and act as a natural process. In this paper, this problem was discussed.
