摘要

陕西汉江流域是"南水北调"中线工程的主要水源地

属于国家重点生态功能区。研究流域内景观格局的时空变化特征、生态系统服务价值和景观生态风险的相关性

对保持流域内生态系统稳定性、保障流域生态安全具有指导意义。基于2000年、2005年、2010年、2015年、2020年陕西汉江流域5期土地利用数据

采用景观格局指数计算、生态系统服务价值评估、景观生态风险评估等方法

研究景观格局变化下生态系统服务价值、景观生态风险的时空演变机制及空间相关关系。结果表明:(1)2000—2020年

流域内景观格局斑块破碎程度降低、异质性和连通性减弱、多样性增加

各地类景观向复杂化方向发展;(2)研究时域内

研究区ESV总体增加5.23亿元

气候调节价值最高

占比41.70%

以较低和中等价值等级为主

占比约61.62%;(3)研究时域内

研究区ESR整体呈小幅减少趋势

降幅1.40%

以较低和中等生态风险等级为主

占比约61.55%;(4)陕西汉江流域生态系统服务价值与生态风险之间存在显著负向空间相关性。景观格局变化使陕西汉江流域生态系统服务功能升高

生态风险降低

两者空间自相关性减弱。

Abstract

The Hanjiang River basin in Shaanxi Province is the main water source of the middle route project of "South to North Water Transfer"

and belongs to the national key ecological functional area. The study of the spatial and temporal characteristics of landscape pattern

the correlation between ecosystem service value and landscape ecological risk in the basin has guiding significance for maintaining ecosystem service function in the basin and ensuring ecological security in the basin. Based on the five phases of land use data of the Hanjiang River Basin in Shaanxi Province in 2000

2005

2010

2015 and 2020

the spatio-temporal evolution mechanism and correlation of ecosystem service value and landscape ecological risk under landscape pattern change were studied by using the methods of landscape pattern index calculation

ecosystem service value assessment

landscape ecological risk assessment

etc. The results showed that: (1) From 2000 to 2020

the fragmentation of landscape patches in the watershed was reduced

heterogeneity and connectivity were weakened

and diversity was increased

and various types of landscape developed towards complexity; (2) In the study time domain

the ESV in the study area had increased by 523 million yuan in general

of which the value of climate regulation is the highest

accounting for 41.70%

mainly in low and medium value grades

accounting for about 61.62%; (3) In the study time domain

the ESR in the study area decreased slightly by 1.40%

mainly at low and medium ecological risk levels

accounting for 61.55%; (4) There was a negative spatial correlation between ecosystem service value and ecological risk in the Hanjiang River Basin of Shaanxi Province. The change of landscape pattern makes the ecosystem service function of the Hanjiang River basin in Shaanxi Province increases

the ecological risk decreases

and the spatial autocorrelation between them weakens.
