摘  要：
生态保护红线的划定对保障干旱区内陆河流域可持续发展具有重要意义,以探讨适宜于该区域的生态保护红线划定方案为目标,选取和田河流域为研究区,在分析该区天然植被分布特征的基础上将其划分为两个不同等级的生态保护红线区,同时采用潜水蒸发法及基流比例法计算从而划定了该区天然植被生态需水红线,生态流量保护红线及地下水保护红线。结果表明:(1)流域天然植被被划分为重点生态功能区和生态敏感区/脆弱区;(2)下游重点生态功能区和生态敏感区/脆弱区主要分布在距河道5~8 km和8~15 km范围内;(3)天然植被生态需水红线为8.85×10~8m~3;(4)在丰、平、枯水年,生态流量保护红线分别为13.79×10~8m~3、12.14×10~8m~3、10.68×10~8m~3;(5)天然和人工绿洲区地下水位红线分别为2.0~4.0 m和2.0~2.5 m,地下水开采量红线为6.07×10~8m~3。本研究不仅为和田河流域"社会—经济—生态"协调发展提供科学指导,也为干旱区相似流域生态保护红线划定提供借鉴。

摘  要：
The delimitation of ecological protection red line is possessed important significance to guarantee the sustainable development of continental river basin in arid zone. Therefore,the objective of this paper was to discuss the suitable delimitation scheme of ecological protection red lines,and choose the Hotan River Basin as study area.Based on analysis of the distribution characteristics of the natural vegetation,the two different grade of ecological protection red line zones were divided,meanwhile the natural vegetation ecological water demand red line,ecological flow protection red line and groundwater protection red line were calculated and delimited by the phreatic evaporation method and base flow proportion method. The results showed that:( 1) The natural vegetation in the Hotan River Basin was divided into the key ecological function area and ecological sensitive or fragile area.( 2) The key ecological function area and ecological sensitive or fragile area in the lower reaches were major distributed 5~8 km and 8~15 km from the river course,respectively.( 3) The natural vegetation ecological water demand red line was 8.85×10~8 m~3.( 4) In the wet year,normal year and dry year,the ecological flow protection red lines were 13.79×10~8 m~3,12.14×10~8 m~3 and 10.68×10~8 m~3 respectively.( 5) The groundwater table red line for natural and artificial oasis were 2.0~4.0 m and 2.0~2.5 m respectively,the groundwater exploitation red line was 6.07×10~8 m~3. This research not only provides scientific guidance for the coordinated development of "society-economy-ecology"in the Hotan River Basin,but also offers reference for the delimitation of ecological protection red lines in similar basin of arid area.
