摘要

[目的

]

分析区域水生生态系统服务功能的价值变化和辐射效应，为区域水资源可持续发展和流域生态补偿提供科学依据。[方法

]

利用ArcGIS软件对2000—2020年河南省洛阳市土地利用数据进行提取得到水域类型面积，采用能值方法对水生生态系统服务功能进行量化，并分析其变化。同时通过断裂点模型分析其功能辐射。[结果

]

2000—2020年洛阳市水生生态服务总能值分别为8.01×10

sej， 1.29×10

sej， 1.27×10

sej， 1.29×10

sej， 1.31×10

sej，总体上呈增长趋势。其中，服务构成重心已由供给功能向文化功能偏移，系统中生物多样性保护、水产品生产、水资源供给、水资源调蓄和休闲娱乐功能居于支配地位，且休闲娱乐功能已成为核心功能。此外，洛阳市水生生态系统服务功能主要转出地区为嵩县和洛宁县，向外转移总量分别为3.10×10

sej和3.21×10

sej，主要转入地区为栾川县、宜阳县、伊川县及汝阳县。[结论

]

在洛阳市同类地区，需要重视水生态保护，加大对区域旅游事业的扶持引导，同时合理地进行流域内生态补偿，促进各地区经济、社会、生态协调发展。

Abstract

[Objective] The value change and radiation effect of the regional aquatic ecosystem service function were analyzed in order to provide a scientific basis for sustainable development of regional water resources and ecological compensation of a river basin. [Methods] ArcGIS software was used to extract land use data for Luoyang City

Henan Province from 2000 to 2020 in order to obtain the area of water type. The emergy method was used to quantify and analyze the changes of aquatic ecosystem service functions

and the functional radiation was analyzed by the break point model. [Results] From 2000 to 2020 (in five-year time steps)

the total emergy values of aquatic ecosystem services at Luoyang City were 8.01×1021 sej， 1.29×1022 sej， 1.27×1022 sej， 1.29×1022 sej， and 1.31×1022 sej

respectively

with a general increasing trend. Among these emergy values

the focus of service composition had shifted from supply function to cultural function. In this system

biodiversity protection

aquatic product production

water resource supply

water resource regulation

and leisure and entertainment functions were dominant. Leisure and entertainment functions have become core functions. In addition

the main transfer areas of the aquatic ecosystem service function in Luoyang City were Songxian County and Luoning County

with total outward transfer values of 3.10×1020 sej and 3.21×1020 sej

respectively. The main transfer areas were Luanchuan County

Yiyang County

Yichuan County

and Ruyang County. [Conclusion] Greater attention will need to be given to ecological protection of water

increasing support and guidance for regional tourism

and reasonably carrying out ecological compensation in areas similar to Luoyang City to promote the coordinated development of the economy

society

and ecology in various regions.
