长江主要支流岸线资源综合评价及管控分区研究

岸线作为与人类密切相关的重要自然资源,在人口、资源、环境和经济发展互动关系中居于核心地位。长江岸线资源作为长江经济带发展的重要支撑资源与重点开发对象,发挥着无可替代的重要生产、生活和生态功能。在长江"共抓大保护,不搞大开发"的背景下,针对长江生态修复的重大科技需求,中国科学院于2017年启动了中国科学院科技服务网络计划(STS)重点项目"长江经济带岸线资源调查与评估"。项目实施以来,项目组通过高清遥感影像解译,结合野外考察和实地监测,获得了长江7条主要支流自然本底、资源条件、利用现状、生态环境的系统数据,以统筹岸线资源开发利用、强化岸线资源保护、维系近岸陆域和水域优良生态环境为目的,研判长江主要支流岸线资源条件及开发利用总体态势,结合岸线生态环境敏感性分析,识别岸线资源利用过程中存在的关键问题,评估岸线的开发利用活动对生态环境的累积性影响。在岸线资源综合评价的基础上,对岸线空间管控区进行划定,提出不同岸线类型管控要求。

Comprehensive Assessment of Water Front Resources of Major Tributaries of the Yangtze River and Study on Control Zoning

Water front resources is an important natural resource closely related to human beings, which is at the core of the interactive relationship among population, resources, environment and economic development. As an important supporting resource and key object of development in the Yangtze River Economic Zone, the Yangtze River water front resources play an irreplaceable important production, life and ecological function. In the context of “joint efforts to protect the Yangtze river rather than develop it”, the Chinese Academy of Sciences launched the “Investigation and Assessment of Water Front Resources in the Yangtze River Economic Zone” project in 2017, which is a key project of the STS program of Chinese academy of sciences, aiming at the major scientific and technological needs of ecological restoration of the Yangtze river. Since the implementation of the project, the project team has obtained the system data of the natural background, resource conditions, utilization status and ecological environment of seven major tributaries of the Yangtze river by means of high-resolution remote sensing image interpretation, field investigation and field monitoring. The purpose of researching and judging the water front resources conditions and the overall development and utilization situation of the main tributaries of the Yangtze river is to coordinate the development and utilization of water front resources, strengthen the protection of resources, and maintain the fine ecological environment of the land and waters near the water front. Based on the analysis of ecological environment sensitivity, the project identifies the key problems in the utilization of water front resources and evaluates the cumulative impact of water front development and utilization activities on the ecological environment. On the basis of the comprehensive evaluation of water front resources, the water front space control zone is defined and the control requirements of different water front types are proposed.
