    摘要:

    [目的] 分析区域山水林田湖生命共同体各要素的耦合协调状态,为更精准开展国土空间规划、生态修复和自然资源要素综合监测提供科学依据。[方法] 以综合评价指数、协调度指数、耦合度指数和关联度指数为基础构建评价分析框架。基于PSR模型,从“山、水、林、田、湖”5个方面构建评价指标体系,运用综合评价模型、耦合协调模型和灰色关联模型探究广西壮族自治区2005—2017年山水林田湖生命共同体的耦合协调时空分异特征及其驱动因素。[结果] ①山水林田湖生命共同体的综合评价指数由2005年的0.918上升至2017年的0.931,具体表现为:水系统 > 田系统 > 林系统 > 湖系统 > 山系统。②山水林田湖生命共同体的耦合协调度由2005年的0.909下降至2017年的0.861,虽然为良好耦合协调状态,但有下降态势。两要素间耦合协调度较高的为“水—田”,3要素间较高的为“水—林—田”,4要素间较高的为“水—林—田—湖”。③影响山水林田湖生命共同体耦合协调发展的主要驱动因素是水要素,灰色关联度为0.723,具体指标因子为水土流失治理。[结论] 山水林田湖生命共同体是一个开放性的“山水林田湖+”的概念范畴,可依据各要素的典型性进行耦合叠加重组,其中水要素是山水林田湖生命共同体各要素耦合关联的核心,水土流失治理是关键因素。广西区内山水林田湖生命共同体综合水平虽然有所改善,但耦合协调情况不容乐观,应以水土流失治理为出发点,串联山水林田湖各要素,进行统筹规划与生态整治,搭建自然资源要素综合监测与质量管理体系,提高耦合协调状态,实现高质量的可持续发展。

    Abstract:

    [Objective] The coupling and coordination status of various elements of the life community of regional mountains, water, forests, fields, and lakes were analyzed in order to carry out more accurate land space planning, ecological restoration, and comprehensive monitoring of natural resources. [Methods] An evaluation framework was constructed based on the indexes of comprehensive evaluation, coordination degree, coupling degree, and correlation index. Based on the PSR model, the evaluation index system was constructed from the five aspects of “mountain, water, forest, field, and lake”. The comprehensive evaluation model, the coupled coordination model, and the grey correlation model were used to explore the spatio-temporal differentiation characteristics and driving factors of the coupled coordination of the life communities in mountains, water, forests, fields, and lakes in Guangxi Zhuang Autonomous Region from 2005 to 2017. [Results] ① The comprehensive evaluation index of the life community of mountains, water, fields, and lakes rose from 0.918 in 2005 to 0.931 in 2017. Specific performance followed the order of water system > field system > forest system > lake system > mountain system. ② The coupling coordination degree of mountain, water, forest, field, and lake life communities decreased from 0.909 in 2005 to 0.861 in 2017. Although the coupling coordination status was considered good, it had experienced a downward trend. The highest combination coordination between two elements occurred for “water-field”. The highest combination coordination among three elements occurred for “water-forest-field”. The highest combination coordination among four elements occurred for “water-forest-field-lake”. ③ The main driving factor affecting the coupled and coordinated development of the life community in mountains, water, fields, and lakes was water, and the gray correlation degree was 0.723. The specific index factor was soil erosion control. [Conclusion] The life community of mountains, water, forest, field, and lake is an open conceptual category of “mountains, water, forest, field, and lake+”. According to the typical nature of each element, a coupling superposition recombination can be carried out, among which the water element is central to the coupling correlation of each element of the life community of mountains, water, forests, fields, and lakes, and soil erosion control is the key factor. Although the comprehensive level of the life community of mountains, water, forests, fields, and lakes in Guangxi has been improved, the coupling coordination is not likely to be good. Soil and water loss control should be taken as the starting point, and all elements of mountains, water, forests, fields, and lakes should be connected to carry out overall planning and ecological renovation. Integrated monitoring and a quality management system of natural resources needs to be developed in order to improve the state of coupling coordination and to realize sustainable, high quality development.
