Abstract

Based on remote sensing image interpretation data of land use/cover change (LUCC) for six periods from 1995 to 2020, we used the equivalent factor method to assess the value of ecosystem services (ESV) in Jiangsu Province and investigated its spatial and temporal evolution characteristics on the grid scale in combination with spatial autocorrelation analysis. The results showed that total value of ecosystem services in Jiangsu Province is on the rise, with an increase of 3.15 billion USD compared with that in 1995. Water area has the largest proportion of ESV and hydrological regulation makes the greatest contribution among ecosystem services, reaching 32.99 billion USD in 2020. The value of ecosystem services measured by the coefficient of sensitivity index of various land use types is as follows: water area>cropland>forestland>grassland>unused Land. Ecosystem service value is positively correlated to spatial distribution, but the correlation is gradually weakening, and the clustering relationship is dominated by high–high and low–low aggregation. The study’s findings will serve as useful guidelines for creating policies in Jiangsu Province pertaining to land use planning and eco-environmental protection.

华东地区江苏省生态系统服务价值的初步评估与时空演变特征

基于1995-2020年六个时期的土地利用/覆盖变化（LUCC）遥感影像解译数据，采用等效因子法对江苏省生态系统服务价值（ESV）进行了评估，并结合空间自相关分析研究了其在网格尺度上的时空演变特征。结果表明，江苏省生态系统服务总价值呈上升趋势，与 1995 年相比增加了 31.5 亿美元。其中，水域面积占生态系统服务总价值的比重最大，水文调节在生态系统服务中的贡献最大，2020 年将达到 329.9 亿美元。用各种土地利用类型的敏感性指数衡量的生态系统服务价值如下：水域面积>耕地>林地>草地>未利用土地。生态系统服务价值与空间分布呈正相关，但相关性逐渐减弱，聚类关系以高高低低的聚集为主。研究结果将为江苏省土地利用规划和生态环境保护政策的制定提供有益指导。

期刊介绍： One of the most important challenges facing the contemporary scientific world are problems connected with environmental protection. Intensive development of industry and agriculture has led to a rise in living standards on one hand, but an increase in environmental degradation on the other. This degradation poses a direct threat to human health and life. Solving these ever-increasing problems which seriously endanger our civilization require the united efforts of scientists and field researchers of many branches. The "Polish Journal of Environmental Studies" publishes original papers and critical reviews on the following subjects: -Basic and applied environmental pollution research, including environmental engineering -Pollution control of atmospheric, water (marine and fresh), soil and biological materials -Determination of harmful substances, including their metabolic breakdown patterns -Analytical methods for metabolic breakdown patterns or other chemical degradation patterns in the environment and in biological samples -Development of new analytical methods, instruments and techniques for controlling pollutants -Circulation of pollutants in the environment and their effect on living organisms -Environmentally oriented catalysis -Hazards to human health and safety -Waste utilization and management -Land reclamation -Conference reports, scientific and technical reports and book reviews
