西部生态环境有其本身脆弱的一面,但环境恶化的主要因素是人的经济活动对环境施加的压力超越了环境的容忍量。治理土地严重退化必须从减轻人对环境的不良影响做起。西部大开发为扭转土地严重退化的局面带来难得的机遇,各级领导和群众应彻底转变观念,处理好环境治理、土地开发和发展经济的关系,创造经济和社会可持续发展的良好环境。随着西部大开发的实施,人类经济活动肯定还要加快。人的因素有两个截然不同的方向,一是片面追求经济的高速增长,不顾环境条件和土地容量,任意开发土地资源,扩大耕地面积和牲畜数量,或者不从根本上解决问题,采取“头疼治头,脚疼治脚”的应付态度,而不顾长远利益,结果必然导致水土流失、土地沙漠化和土壤盐碱化继续严重发展,流沙扩展,水蚀黄土和石灰岩地区的劣地继续发展,而绿洲地区土壤大片盐渍化。最终只能退出西部大多数地区;二是自觉地约束自身的行为,把人对生态环境的干扰变成促进生态环境和经济协调、和谐发展的行为。认真贯彻西部大开发生态建设优先的方针,全面规划,采取有力的措施治理失衡的环境,使西部的环境达到“山川秀美”。
The western ecological environment has its own fragile side, but the main factor of environmental deterioration is that the pressure of human economic activities on the environment exceeds the tolerance of the environment. To control the serious land degradation, we must start from reducing the adverse effects of human beings on the environment. The great development of the western region has brought a rare opportunity to reverse the serious land degradation. Leaders and the masses at all levels should completely change their ideas, deal with the relationship between environmental governance, land development and economic development, and create a good environment for sustainable economic and social development. With the implementation of the western development, human economic activities must be accelerated. Human factors have two distinct directions. One is to pursue the rapid economic growth unilaterally, develop land resources arbitrarily, expand the cultivated land area and the number of livestock regardless of the environmental conditions and land capacity, or not fundamentally solve the problem, adopt the coping attitude of "headache to treat the head, foot pain to treat the foot", regardless of the long-term interests, the result will inevitably lead to soil erosion, land desert Soil salinization and salinization continue to develop seriously, quicksand expands, and poor land in water eroded loess and limestone areas continues to develop, while large areas of soil salinization in oasis areas. Finally, we can only withdraw from most of the western regions; secondly, we should consciously restrict our own behavior, and turn the interference of human beings to the behavior of promoting the coordinated and harmonious development of ecological environment and economy. We should conscientiously implement the principle of giving priority to ecological construction in the development of the western region, make a comprehensive plan, and take effective measures to control the unbalanced environment, so as to make the environment in the western region "beautiful in mountains and rivers".
