Study On Hydro-eco Characteristics And Rational Utilization Of Water Resources In The Continental River Of Arid Area

The continental river watershed of arid area lies in the hinterland of the Eurasian continent, far from the seas with relatively closed topography, dry climate, low precipitation and high evapotraspiration. Because of no-rational utilization of water resources, the continental river watershed of arid area had appeared water use contradictory protruding, Eco-Environment worsen, it restrict the west region exploitation strategy and reconstructing a new northwest region of graceful landscape with green and beautiful mountains, affect the utilization of resources in the continental river watershed of arid area, the improvement of people life level, threaten sustainable development of region society economy and society stable. The continental river watershed of arid area mainly exploits water resources in plain area, which mostly stem from the continental river of arid area. It can rational utilization of water resources, promote the west region exploitation strategy and reconstructing a new northwest region of graceful landscape with green and beautiful mountains, when we know basic law and watershed Eco-Environment change law.Based on existed achievements of the continental river of arid area, the paper system analysis hydro-eco characteristics, hydro-eco changes and watershed changes. A case in Tarim river, the paper study hydro-eco characteristics, river evolution, evaluated Eco-Environment quality, explore ecology water demand, study the rational utilization of water resources in Tarim river watershed.The paper is composed of nine chapters, chapter 1 include research background, main research contents, research methods and research, meaning. Academic research and development in the continental river of arid area are presented at home and abroad, as well as bring forth new ideas.Chapter 2, the author illuminates briefly nature geographical situations of the continental river of arid area, analysis formation condition, recharge condition, dischargecondition of the continental river, hydro-eco characteristics of the continental river of arid area.Chapter 3, the paper studied climate changes, hydrology changes, water quality changes, sediment changes, water volume changes along route on the continental river of arid area.Chapter 4, the paper analysis hydro-eco changes on the continental river of arid area how to affect lake, groundwater, vegetation, animal, partly climate, etc.Chapter 5, the author study hydro-eco evolution and watershed Eco-Environment changes of Tarim river, analysis the reason of hydro-eco changes about Tarim river according to geographic characteristics and hydrology characteristics of Tarim river.Chapter 6, the author explore the calculation methods of ecology water demand about nature vegetation, river, lake in Tarim river watershed.Chapter 7, based on vulnerable ecology of Tarim river watershed, the author build Eco-Environment quality evaluation fuzzy synthetical evaluation model according to Tarim river watershed characteristics.Chapter 8, the author analysis rational utilization of water resources in Tarim river watershed, put forward rational utilization principle, countermeasures, measures in accordance with present situation and existed problem of water resources exploitation in Tarim river watershed.Chapter 9 is composed of main conclusions and advices for the continental river of arid area.
