冰冻圈水资源服务功能区划研究综述

冰冻圈作为气候系统五大圈层之一,是我国干旱区和寒区重要的水源地和固态水库,对生态、水、环境及气候等均具有重要影响。长期以来对冰冻圈产品及社会经济服务功能研究不足,遑论从地域主体功能角度对冰冻圈水资源服务功能进行区划。水资源服务作为冰冻圈资源的重要功能,是进行冰冻圈服务功能及其区划研究的重要突破口。基于冰冻圈科学、人文地理学、生态学等多学科交叉的理论和方法,重点从冰冻圈水资源分布与监测、地域功能区划、水资源服务功能分类和评估等三个方面进行了研究综述,并提出了生态系统服务功能与三生空间研究相结合的冰冻圈水资源服务功能分类体系和基于冰冻圈水资源特性、供给能力、社会经济发展水资源需求和利用效率的冰冻圈水资源服务功能评估指标体系。最后基于研究综述、已构建的冰冻圈水资源服务功能分类和评估体系,综合已有的自然地理综合区划、地域功能区划等区划实践,并探讨了未来可行的冰冻圈水资源服务功能研究方案设想,为进行全国乃至全球的冰冻圈水资源服务功能区划工作提供了理论与实践基础。

Theory and Practice of Soil and Water Ecology

Author of this paper introduced the formation and development, main viewpoints, and framework of the theory of soil and water ecology, as well as the role and value of realizing the sustainable utilization of soil and water ecological resources, the sustainable maintenance of ecological environment, and the sustainable development of economy and society. The paper argued that in the current era, it is imperative to maintain the integrity and continuity of soil and water ecology and culture, emphasize the planning and construction of soil and water ecological infrastructure, and ensure the service functions of urban ecosystem, so as to realize the sustainable utilization of soil and water ecological resources, and the sustainable maintenance of ecological environment, and the sustainable development of economy and society.
