Research on water compensation mechanism for typical alpine plant communities under frozen-soil un-derground reservoirs in three-river source area:a review
摘要
Abstract
Three‐River source area ,as a national nature protection area ,the changes of permafrost have caused some problems in alpine ecosystem and these problems have been paid great attention to in recent years .This paper reviewed the research of water compensation mechanism for typical alpine plant communities under frozen‐soil underground res‐ervoirs based on the interdependence between permafrost underground reservoir and plant community in Three‐River source area:(1) The typical vegetation in Three‐River source area has an important ecological value for regional eco‐logical environment and special environment determines the distribution characteristics of vegetation .(2) The pattern of frozen‐soil underground reservoir is put forward on the basis of the basic building conditions of underground reser‐voirs in permafrost active layer of Three‐River source area .(3) There is relevant coupling relationship between perma‐frost and vegetation in Three‐River source area .(4) The researches on the distribution of permafrost active layer ,the characteristics of soil moisture content in permafrost ,the runoff hydrological processes in frozen area provide the theo‐retical basis to explain the general research .And (5) geological radar with the advantages of no damage ,accuracy , high efficiency and portable carrying ,is a better detection technology in frozen soil survey .The focused research ques‐tions on the permafrost are pointed out from the perspective of underground reservoir ,including water compensation mechanism of frozen‐soil underground reservoirs to plant communities ,building conditions of frozen‐soil underground reservoirs ,stable hydrating mechanism of discharge characteristics of frozen‐soil underground reservoirs to alpine plant communities ,ecological effect of underground reservoirs on alpine vegetation ,and application of geological radar in fro‐zen soil monitoring .Finally ,the general research ideas are proposed from the perspective of stable water compensation mechanism of permafrost underground reservoirs in hope of directing the ecological environment in Three‐River source area .关键词
