摘要:
[目的] 对新疆阿克苏地区生态源地进行识别,为该地区生态安全格局构建和可持续的国土空间生态修复提供策略与建议。[方法] 以新疆阿克苏地区为例,采用定性(生态保护红线直接识别法)和定量(基于InVEST模型的综合评估法)方法识别生态源地,并在此基础上,比较两种结果之间的差异及其原因,判定目前划定的生态保护红线能否体现人类对生态系统服务需求。[结果] ①基于InVEST模型的综合评估法识别的生态源地面积为11 433.6 km2,占研究区总面积的8.9%,主要分布于区内河流及其周边区域;基于生态保护红线直接识别的生态源地面积为22 746.8 km2,占研究区总面积的17.7%,主要分布于天山南麓和区内河流周边区域;②两种方法界定的生态源地在空间分布在上存在着较大差异。综合评估法界定的生态源地中有59.4%不在生态保护红线内,面积为6 787.0 km2。③导致两种结果差异的主要原因在于生态保护红线侧重于对生态用地本身生态功能的保护,而生态源地的概念结合了人的需求,更侧重于各类生态系统为人类生产生活提供的服务。[结论] 未来的工作中,需要考虑如何将侧重满足社会需求的生态源地与侧重生态环境保护的生态红线相统一,应选择以定量识别生态源地为主,以定性识别生态源地为辅,综合划定生态源区,并提出潜在的规划和政策建议,以实现社会经济和自然环境的协调发展。

Abstract:
[Objective] The ecological source area was identified in Akesu area, Xinjiang Uygur Autonomous Region, in order to provide strategies and suggestions for the construction of the ecological security pattern of the region and the sustainable ecological restoration of the land and space. [Methods] Taking Aksu area in Xinjiang as an example, the ecological source area were identified by quantitative method (comprehensive evaluation method based on the InVEST model) and qualitative method (the ecological conservation redline was identified in the direct way). On this basis, the differences between the two results and their causes were compared to determine whether the ecological protection red line could reflect human demand for ecosystem services. [Results] ① The ecological source area identified based on the comprehensive evaluation method using the InVEST model was 11 433.6 km2, accounting for 8.9% of the total area, mainly distributed in the rivers and surrounding areas. The ecological source area identified directly based on the ecological conservation redline was 22 746.8 km2, accounting for 17.7% of the total study area, mainly distributed in the south of Tianshan Mountain and surrounding areas of rivers. ② There are great differences in the spatial distribution of the ecological source areas identified by the two methods. About 59.4% area of the ecological source identified by comprehensive evaluation was not in the ecological conservation redline, occupying 6 787.0 km2. ③ The main reason for the difference between the two results was that the ecological conservation redline focused on the protection of ecological functions of the ecological land, while the concept of ecological source combined the requirements of human beings, and prefered the services that the ecological system provided to human production and living. [Conclusion] In the future, it is necessary to consider how to unify the concept of the ecological source areas that focus on meeting the social requirements with the ecological conservation redline that focus on the ecological environment conservation. We should define the ecological source in a comprehensive manner, based on the quantitively identified ecological source as the primary factor and the qualitatively identified ecological source as the secondary factor, and propose advices for potential plans and policies to realize the coordinated development of the social economy and natural environment.
