摘要
Abstract
The construction and operation of Haibowan Water Control Project has an irreversible impact on the Tourism Area of Populus Euphratica Island of the West Erdos.Through the relevant investigation,the species distribution area of Populus euphratica is 2.31 hm2 with the total plant-number of 1 800,while the population of Populus euphratica exhibits increasing characteristics with a total biomass of 95.43 t.The submerged period of the island is to be prolonged after the operation of Haibowan Water Control Project along with significant increases of the submerged depth and area,even the lower location of the north part of the island is to be submerged all year around.A part of the seeds are possibly to fall into water and be carried away by water flow,thus lose their propagation condition.Furthermore,the adventitious buds of the root sucker are to be also submerged in water during the growth period from April to June,and then are unable to finish their asexual propagation.Moreover,the saplings of Populus euphratica with the height lower than 2.5m cannot survive after inundation.The reservoir inundation makes the ecosystem of the island that mainly consists of terrestrial ecology-based ecosystem evolve into an ecosystem that mainly consists of aquatic ecology-based ecosystem,thus the original tourist functions are to be changed or lost,and then the relevant eco-compensation measures must be made,so as to reduce or remit the eco-impact caused by the project.关键词
