QUANTITATIVE ANALYSIS OF THE IMPACTS OF CLIMATE CHANGE AND HUMAN ACTIVITIES ON ECOLOGICAL QUALITY: A CASE STUDY OF HAINAN ISLAND
-
摘要: 气候变化和人类活动在生态系统变化中产生协同影响,难以区分。以海南岛为案例,使用残差趋势法,测量生态质量实际和潜在趋势的残差,量化气候变化和人类活动的相对贡献。结果表明:2002—2020年海南岛生态质量总体呈上升趋势,其中54.09%区域生态质量呈显著改善趋势,而4.33%区域生态质量呈显著下降趋势。人类活动对海南岛生态质量变化的贡献率为85.93%(P<0.05),而气候变化对海南岛生态质量变化的贡献率为14.07%(P<0.05)。人类活动在海南岛生态质量变化中起到了主导作用。生态质量改善区域,森林生态系统增加、农田生态系统减少,主要人类活动为先后实施海防林建设、人工商品林建设、生态保护红线划定等生态保护措施,如临高县等;而生态质量下降区域,森林生态系统减少、农田和城镇生态系统增加,主要人为活动为开垦开发建设活动,如海口市等。研究成果对于科学管理生态系统和应对气候变化具有重要意义。Abstract: The synergistic effects of climate change and human activities on ecosystem changes are difficult to distinguish. Focusing on this scientific issue, this study uses Hainan Island as a case study to measure the residuals of actual and potential trends in ecological quality, and quantify the relative contributions of climate factors and human activities with the residual trend method. The results show that the overall ecological quality of Hainan Island has been on an upward trend from 2002 to 2020, with 54.09% of the regional ecological quality showing a significant improvement trend, and 4.33% showing a significant decline trend. The contribution rate of human activities to the change in ecological quality on Hainan Island is 85.93%(P<0.05), while the contribution rate of climate change is 14.07%(P<0.05).Human activities have played a dominant role in the change of ecological quality on Hainan Island. Areas experiencing ecological quality improvement have seen a rise in forest ecosystems and a corresponding decline in farmland ecosystems. The main anthropogenic activities responsible for this are the sequential implementation of coastal defense forest construction, commercial plantation establishment, and the delineation of ecological protection red lines, such as Lingao County. Areas experiencing a decline in ecological quality have witnessed a reduction in forest ecosystems accompanied by an expansion of farmland and urban ecosystems. The primary human activity leading to this change is land reclamation and urban development through construction activities, such as Haikou. This study is of great significance for the scientific management of ecosystems and the response to climate change.
