摘要

生态系统质量是区域探索生态优先、绿色发展为导向的高质量发展的重要基础。开展区域生态系统服务评估可获取国土空间生态本底特征，为生态系统保护格局构建提供现状底图，明确生态系统修复重点、国土空间优化提供导向。以长汀县为例，基于地区生态典型性、区域生物量差异及公众支付意愿与能力构建特色评价指标，采用生态承载力与生态系统生产总值耦合研究方法，对长汀县生态系统服务进行县域、镇域、村域及系统斑块等多尺度评估。结果表明：长汀县生态系统服务等级空间分布符合区划规律，大致呈中间低、四周高的特征；尺度细化使结果分布异质性更强，可为开展生态修复、空间优化提供更具针对性的建议；长汀县生态系统较为脆弱，低生态等级乡镇个数占比高达38.89%，影响因素多样，水土流失及森林覆盖率影响显著；地形地势、人类活动、政策实施影响生态承载力的空间分布，地势平坦的人口稠密区系生态承载力低值集中区；森林生态系统在生态系统生产总值评估中扮演重要角色，生态系统生产总值均值等级极高的4个乡镇，其森林生态系统面积皆占89%以上。通过对生态承载力与生态系统生产总值耦合的方法进行探究，有利于推进"两山"理论的应用实践，将为地区生态系统服务提升与空间发展提供参考建议。

Abstract

Ecosystem quality is essential for the region to explore new high-quality development methods with ecological priority and green development-oriented. Carrying out regional ecosystem service assessment can obtain the land space's ecological background characteristics

provide a base map of the status quo for the construction of ecosystem protection patterns

clarify the focus of ecosystem restoration

and provide guidance for the optimization of land space. This study concentrated on the Changting County of Fujian Province and attempted to explicitly elucidate its ecosystem services at the county

town

village

and system patch scales. Our methodology's distinctive contribution was that we coupled the ecological carrying capacity and gross ecological product approaches and set specific evaluation indicators based on regional ecological representativeness

regional biomass differences

and public willingness to pay and competence. The results showed that the ecosystem services grade conformed to the zoning rules

roughly appearing the low characteristics in the middle and high in the surroundings. Refinement of the scale made the distribution of results more heterogeneous

providing targeted suggestions for ecological restoration and space optimization. The ecosystem was relatively fragile in Changting County

with low ecological level townships accounting for as high as 38.89%. The influencing factors were diverse

among which soil erosion and forest coverage had a significant impact. Topography

human activities

and policy implementation affected the spatial distribution of ecological carrying capacity

and densely populated areas with flat terrain were concentrated areas with low ecological carrying capacity. Forest ecosystems value was the dominant part of the gross ecological product in Changting County. The forest ecosystem area accounted for more than 89% in the four townships with extremely high average gross ecological product level. The methodology applied in the study could help promote the application and practice of the "two mountains" theory. Our findings will provide recommendations on regional ecosystem services function improvement and spatial development.
