摘要
从绿洲形成演变过程、绿洲气候效应、绿洲农业研究和绿洲生态环境保护 4个方面 ,对国内外绿洲研究现状进行了简略回顾。分析后发现 ,虽然绿洲研究的成果颇丰 ,但也存在以下三方面问题 :首先是概念认识上的混乱以及由此而导致的其它延伸性错误 ;其次人工绿洲研究相对要多一些 ,程度也更深入一些 ,但天然绿洲的研究则较为薄弱 ;第三 ,研究视野较小 ,所获结果缺乏与其它相关区域的对比分析 ,因而不能够判定其实际价值。在研究工作存在分岐的同时 ,所有研究者均承认绿洲是一种景观 ,但是从该角度进行研究的工作却鲜有报导 ,因此 ,绿洲景观方面的研究应是发挥交叉学科优势。
From four aspects, that is, the formation and development process of oasis, the climatic effect, the research on the oasis agriculture and the ecological environment protection of oasis, the author reviews summary of the status of the research on oasis at home and abroad. Through analyses, the authors find that the research on oasis exists following three problems in spite of the rich achievements. The first is the confusion of conception which goes a step further to result in the other derative mistaken. The second, although the research on the man made oasis is deeper comparatively and so does its outcome, the research on the nature oasis is rather weak. The third, due to the narrowness of the research vision and the lack of comparative analysis with other relevant region, the practical value of former research result cann't be determined. Although there exist divergences in the oasis research, the author find that there is a common base in works which is that researcher on oasis all consider that the oasis is one types of landscape in arid region, but there is a few research work on this aspects. We think this is a very important research direction.
