摘要
根据历史和现代研究资料,系统分析了影响黑河流域绿洲演变的自然和人文因素。自然因素包括气候、地质地貌、风沙活动及自然灾害等方面,是绿洲演变的大背景。人文因素包括战争、民族习惯与政府政策导向,交通、政治、经济地位,人口压力及资源需求的增长。人文因素是十分错综复杂的,自人类社会形成以来就愈来愈强烈,而且加剧自然因素的作用程度与范围,甚至在一定时空条件下完全可以掩盖自然因素对绿洲的作用。基于上述认识,认为对于整个流域来讲,上、下游应将水源涵养和生态保护作为建设重点,中游作为经济建设的重点区域,上、中、下游优势互补、共同发展,达到整个流域资源、环境、经济的可持续发展。
The natural and human factors that influence the oasis evolution of Heihe river basin are analyzed systematically based on the historical and modern research data. The natural factors include climate, geology, sand-blowing activity and natural disasters. The human factors include war, national custom, policy, traffic, economic position, population and needs for natural resources. Human factors are very complex, whose degree and extent are becoming more serious and larger with time in influencing the oasis evolution; and even could cover up the effect of the natural factors in certain conditions. As to the development of whole Heihe river basin the water conservation in the upper reaches and the ecological protection in the lower reaches must be firstly taken into consideration; the middle reaches as the emphasis region for economic construction. Only these three regions form complementary pattern and develop harmonized would the whole basin realize the sustainable development of resources, environment and economy.Key words: Heihe river basin; oasis; environmental evolution; influencing factors
