The eco-environment of Manwan reservoir is frail and apt to deterioration because of its abrupt slope,developed faults,topographic unconformity and concentrated rainfall.Based on site investigation and statistics analysis.It is elaborated on several aspects of the reservoir's ecological degradation:① landscape change.Villages,cropland,terrestrial life formerly in the valley blow the elevation of 994?m were inundated;while forest,grassland and grading slope from 1?000?m to 1?800?m were replaced by newly-reclaimed sloping fields and newly-established concentrated settlements.The eco-environment tends to be frailer,whereas the reservoir's hydrothermal change after impounding provides better conditions for vegetation from 1?000 to 1?300?m,hence contributes to its restoration;② After 1984,soil erosion in the slope land around the reservoir area have been more serious.The annual sediment concentration in the river flow was increased by 36.6%,and annual sediment flow increased by 37.3%;③ serious loss of the reservoir's storage capacity.According to the survey in 1998,after 3 years' operating,the loss of the active storage reached at the level that expected after 15 years of operation;④ frequent occurrences of soil-and-water loss,landslide,mudflow,torrential flood as well as collapse.Based on further analysis on human factors leading to ecological deterioration,it could be found that:① slope reclamation brings about the loss of vegetation and the worsening of soil erosion;② filling and releasing of reservoir make the surrounding area less stable and be apt to collapse and landslide;③ infrastructure development of highway and irrigation projects results in landslide and mudflow;④ the reservoir's sediment concentration and water pollution are closely related to upstream environmental depression.Finally,to reduce the ecological deterioration's negative effect on local production,life as well as the reservoir's economic life,and to maintain the ecosystem of the reservoir and improve the local farmers' life conditions,five countermeasures have been put forward:① resettle those who reside in the deteriorated area and those who suffer from landslide and mudflow in places beyond the reservoir area.Currently,the affected population is about 1?000,with a resettlement cost of 30 million;② regarding small basin as ecological unit,combine reasonable land use,disaster control and community development together to carry out comprehensive regulation,with emphasis on Gonglang River in Nanjian and Heihe River in Fengqing county;③ strengthen the harnessing of resettlement areas and key disaster-hazard regions;④ increase maintenance cost for Manwan hydropower station,supporting afforestation engineering,rural resources exploitation and poverty alleviation programme in resettlement areas;⑤ harness water-contaminating enterprises in Dali city and Lanping county to improve the inflow quality;⑥ along with the construction of Xiaowan's large-scale power station,speed up natural forest engineering and soil-and-water loss control along banks of upper-and mid-Lancang River.

漫湾库区多陡坡,断层发育,地表破碎,雨量集中,生态环境较为脆弱,易退化.通过实地调查及野外资料分析,介绍了该库区生态退化的几个表现:①景观变化,原994m以下河谷地带的村落、耕地、陆生动植物全部被淹没,在1000~1800m的谷坡地带,原有林地、草地、坡度稍缓的地方,均被新开垦的坡耕地和新建的聚落环境所取代.生态环境较以前脆弱,但因蓄水后库区水热配置条件的改变,使1000~1300m地带的植被条件变好,促进了库区植被的恢复;②1984年以后,库区及上游地区地表水土流失加剧,长系列年径流量含沙量增加36.6%,年输沙量增加37.3%;③库容损害严重,1998年调查,水库建成的3年时间里,总库容淤损率已达到原设计标准的第5年水平,有效库容淤损率已达到15年的水平;④水土流失、滑坡、泥石流、山地洪水、崩塌等山地灾害频繁.并进一步分析了造成生态退化的人为因素,认为:①建库后坡地开垦,造成库区植被的减少,以及水土流失的加剧;②水库蓄放水造成库周边稳定性变弱,引起崩塌和滑坡;③因公路、水沟等水库相关工程设施建设引起泥石流等山地灾害;④库外上游环境恶化是库区泥沙、水质生态环境的重要影响因素.最后,例举库区生态环境恶化对地方...

There are many coupling systems of mountain-oasis-desert in Xinjiang. As the important factors to the coupling relationship of three systems,the characteristics of three systems affecting the coupling characteristics, coupling relations,physiognomy patterns,vegetation and climate are very important to the coupling of the three systems. The types of physiognomy and the characteristics of climate determine the base and the frame of coupling types,and the hydrologic characteristics determine the spatial pattern of coupling types,and the vegetation types determine the color of coupling types. It is important for the sustainable development in such arid region to contrast and discuss the difference between the three systems and the characteristics of climate change. By analyzing the characteristics of the three systems in MODS,and combining the characteristics of the climate, we obtain the conclusions as follows:( 1)The structure of mountain systems is complicated, and the complicated environment creates the abundant biodiversity,and the hydrothermal change laws and the vertical natural zones are very obvious. The oasis systems are the artificial compound ones,and the complicated and high effects and the huge productivity are the basic characteristics.The desert systems also show some characteristics,such as the simple structure,poor stability and low productivity.(2)There are great differences among the three systems in MODS,but the three systems are not isolated,MODS is a compound system,and the three systems are connected by material current,energy current and information current.(3)The vegetation types in the south Xinjiang are the same with that in north Xinjiang,but the altitudes of the same vertical zone in south Xinjiang and north Xinjiang are different. The oasis vegetation is different from the different conditions of exploitation and utilization of water resources.There is a great difference in vegetation types and biomasses between north Xinjiang and south Xinjiang.(4)Both south Xinjiang and north Xinjiang are located in the arid regions in northwest China,but the climate is different due to the different latitudes and physiognomies.The average temperature in south Xinjiang is higher than that in north Xinjiang,but the precipitation in north Xinjiang is three to four times higher than that in south Xinjiang.These hydrothermal differences affect undoubtedly the physiognomies,vegetation types and the hydrological characteristics,thus the difference of MODS coupling characteristics between north Xinjiang and south Xinjiang forms.

在位于中国西北内陆干旱区的新疆,发育着大量的山地-绿洲-荒漠系统,山地系统是干旱区水资源的形成区,也是重要的矿质营养库和生物种质资源库,绿洲系统是生产力相对较高的区域和人类赖以生存和发展的中心,而荒漠系统则是干旱区面积广阔和环境相对恶劣的区域。地貌类型与气候特征决定耦合类型的基础和框架,水文特征决定耦合类型的空间格局,植被类型反应耦合类型的外貌。通过对新疆山地、绿洲、荒漠三个子系统结构与功能进行了分析,并结合新疆近40年气候变化的特点和规律,来探讨中亚干旱区山地-绿洲-荒漠系统的特征。
