Abstract:

Based on the data of land use and land cover change in 2000, 2010 and 2018, the temporal and spatial evolution characteristics of the landscape pattern and ecosystem services in the Hanjiang Eco-Economic Belt were measured, and the impact of the landscape pattern index on ecosystem services was explored by using a geographically weighted regression model. The results showed that: (1) From 2000 to 2018, the landscape pattern of the Hanjiang Eco-Economic Belt changed significantly, the degree of fragmentation and decentralization of each landscape type deepened, and the shape became more complex. (2) The ecosystem service value of the Hanjiang Eco-Economic Belt showed a trend of first increasing and then decreasing, with the overall characteristics of being high in the central and western regions and low in the eastern regions. (3) From 2000 to 2018, the landscape pattern index of the Hanjiang Eco-Economic Belt had a significant impact on ecosystem services, but the impact on different regions was quite different. On the whole, PD, ENN_MN, SPLIT, and SHDI had negative effects on ecosystem service value, while IJI had positive effects on ecosystem service value. The study is helpful to enhance the scientific understanding of the relationship between the landscape pattern and ecosystem services on a county scale and provides a scientific basis for exploring the influencing factors of regional landscape ecological security and implementing ecological protection policies.

Key words: ecosystem services value, landscape pattern, geographically weighted regression, Hanjiang Eco-Economic Belt

摘要:

基于2000、2010、2018年3期的土地利用/土地覆被变化数据测度了汉江生态经济带景观格局和生态系统服务的时空演变特征,并采用地理加权回归模型探究景观格局指数对生态系统服务的影响。结果显示:(1)2000—2018年间,汉江生态经济带景观格局变化显著,各景观类型破碎化、分散化程度加深,形状愈加复杂化;(2)汉江生态经济带生态系统服务价值呈现先升高后降低的趋势以及中西部高、东部低的总体特征;(3)汉江生态经济带景观格局指数对生态系统服务影响显著,但对不同地区的影响存在较大差异。总体上看,斑块密度(PD)、平均最邻近距离(ENN_MN)、分离度(SPLIT)和香农多样性指数(SHDI)对生态系统服务价值的影响大致呈现负效应,而散布与并列指数(IJI)对生态系统服务价值的影响总体呈正效应。研究有利于增强对县域尺度上汉江生态经济带景观格局与生态系统服务关系的科学认知,为探究区域景观生态安全影响因素、落实生态保护政策提供科学依据。
