Abstract
Understanding the response mechanism of ecosystem services (ES) to landscape patterns is important in regional landscape planning and sustainable development. In this study, the landscape index and InVEST model were used to quantitatively analyze the spatio-temporal evolution of landscape patterns and ES in the Ganjiang River Basin of China from 1990 to 2020. Furthermore, the bivariate Moran's I method and spatial error model were used to test the spatial correlation between landscape index and ES. The results showed that (1) cropland decreased and construction land increased, and the overall landscape tended to be fragmented, the patch shape complicated, and landscape diversity increased from 1990 to 2020. Water conservation (WC) and soil conservation (SC) capacity increased by 10.56 mm and 16.24 t hm-2 a-1, respectively, whereas carbon storage (CS) decreased by 1.22 t hm-2 a-1. (2) The responses of different typical ES to landscape patterns were different in the landscape index and response degree. Typical ES negatively responded to Shannon's diversity index and patch density. WC was sensitive to the Splitting Index, whereas SC and CS were more responsive to the average patch area. (3) The overall purpose of territorial spatial planning within a basin should be to reduce the fragmentation and heterogeneity of the landscape. According to four local aggregation patterns of landscape index and ES, corresponding measures can be taken according to local conditions in different regions. These results can provide a quantitative basis for landscape management and ecological construction in the Ganjiang River Basin and scientific guidance for the Yangtze River conservation strategy.

Zhang J, Zhang D. Study on the fundraising of horizontal ecological compensation under efficiency and fairness: a case study of the Yellow River Basin in China. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023:10.1007/s11356-023-27656-0. [PMID: 37209346 DOI: 10.1007/s11356-023-27656-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 05/11/2023] [Indexed: 05/22/2023]
Abstract
How to raise the ecological compensation fund for the Yellow River Basin is one of the key difficulties for executing the ecological compensation mechanism and ensuring the high-quality development of the entire basin. This paper, which is based on systems theory, analyzes the social-economic-ecological compound system of the Yellow River Basin. It makes the point that the goals of human-water harmony, ecological compensation efficiency improvement, and coordinated regional development should be achieved in raising ecological compensation funds. Guided by the raising targets, a two-layer fundraising model based on efficiency and fairness is constructed for ecological compensation. The upper-level model is built to calculate the ecological compensation efficiency of each compensation subject from an input-output perspective. The initial fundraising scheme was further determined to implement the efficiency principle. Within the framework of sustainable development theory, the lower-level model adheres to the fairness principle based on efficiency. The social-economic development level of the compensation subject is considered to discriminate and optimize the initial scheme. Additionally, the two-layer model was utilized to conduct an empirical analysis with the data of the Yellow River Basin from 2013 to 2020. The results show that the optimized fundraising scheme is in line with the actual development level of the Yellow River Basin. This study can provide a reference for the fundraising of horizontal ecological compensation and promote the sustainable development of the whole basin.
