    摘要:

    [目的] 揭示山水林田湖海各要素之间的耦合协调效应关系及其驱动力因素,为更精准地开展陆海统筹生态修复工作提供科学依据。 [方法] 以广西北部湾为研究区,运用综合评价指数、耦合指数、协调指数、灰色关联指数(“4C指数”),从山、水、林、田、湖、海6个子元素构建评价单元体系,揭示其各要素间的相互作用、综合发展水平、耦合协调情况,分析广西北部湾山水林田湖海生命共同体耦合协调分异特征及其驱动因素。 [结果] ①2005-2020年,广西北部湾山水林田湖海生命共同体综合评价指数上升了0.246 6,具体表现为:水系统>林系统>海系统>湖系统>田系统>山系统。 ②2005-2020年广西北部湾耦合协调度上升了0.160 5,其类型表现为:初级协调-中级协调-良好协调的耦合协调演变过程。 ③灰色关联度高的是水系统和田系统及其子指标,灰色关联度分别为0.666 7,0.634 1。 [结论] 广西北部湾山水林田湖海生命共同体的主要驱动因子是水田系统和田系统。未来研究需以田、湖、水系统综合整治入手,发展海洋特色产业,注重海洋生态修复,减少山、田、湖系统对区域发展的制约,强化生态资源的保护,使其向可持续方向展开。

    Abstract:

    [Objective] To reveal the coupling and coordination effect relationship and driving factors among the elements of mountain, water, forest, field, lake and sea, and to provide scientific basis for more accurate ecological restoration work on land and sea. [Methods] Taking Beibu Gulf Guangxi as the research area, the comprehensive evaluation index, coupling index, coordination index and grey correlation index (“4C index”) were used to construct the evaluation unit system from the six sub-elements of mountain, water, forest, field, lake and sea, to reveal the interaction, comprehensive development level and coupling coordination of each element, and to analyze the coupling of the life community of mountains, water, forest, field, lake and sea in Beibu Gulf Guangxi The characteristics of coordination differentiation and its driving factors. [Results] ① From 2005 to 2020, the comprehensive evaluation index of the life community of mountains, rivers, forests, fields, lakes and seas in Beibu Gulf Guangxi increased 0.246 6, as follows: water system > forest system > sea system > lake system > field system > mountain system. ② From 2005 to 2020, the coupling coordination degree of Guangxi Beibu Gulf increased by 0.160 5, which showed a coupling coordination evolution process of “primary coordination,intermediate coordination and good coordination”. ③ The high grey correlation degree of water system and field system and their sub-indexes is 0.666 7 and 0.634 1, respectively. [Conclusion] The main driving factors of the life community of mountains, rivers, forests, lakes and seas in Guangxi Beibu Gulf are the paddy field system and the paddy field system. The future researches need to start with the comprehensive renovation of the fields, lakes and water systems, develop the marine characteristic industries, pay attention to the marine ecological restoration, reduce the restriction of the mountain, field and lake systems on the regional development, strengthen the protection of ecological resources, and make it develop in a sustainable direction.
