Analysis of Green Development Dynamics and Influencing Factors in Daihai Basin

Green development accounting provides the theoretical basis and data support for national or regional ecological civilization constructions. The Daihai Basin, located in Ulanqab City, Inner Mongolia Autonomous Region, is not only an important ecological barrier in the region but also one of the 179 nationally important wetlands under the “China Wetland Conservation Action Plan”. It plays a crucial role in maintaining regional ecological balance, providing ecological services such as water conservation, climate regulation, and biodiversity protection. Taking Daihai Basin as the study area, an accounting system of Green Gross Domestic Product (GGDP), Gross Ecosystem Product (GEP), and Gross Economic–Ecological Product (GEEP) was constructed to explore the temporal variation characteristics of GGDP, GEP, and GEEP in the study area from 1989 to 2022. The results were as follows: (1) During the study period, the overall GGDP in Daihai Basin showed an increasing trend, with an increase of CNY 3.812 billion in the past 30 years, of which GGDP increased from 1989 to 2011 and decreased from 2011 to 2022. In addition to GDP, the ecological damage cost was the most important factor influencing GGDP in the Daihai Basin, and the most significant one is the ecological damage to the wetland. (2) The GEP in the study area decreased, with a decrease of CNY 1.066 billion in the past 30 years. However, the conversion value of “Two Mountains” increased year by year. During the study period, the ecological regulation service value, which was dominated by climate regulation and water conservation, decreased year by year. (3) The GEEP in the study area showed a fluctuating change, with an overall upward trend, reaching a maximum of CNY 9.011 billion in 2011. (4) Except for 2011, during the study period, GEEP > GEP > GGDP in Daihai Basin, but the main driving factors of the three indicators were different, and the variation trends with time were different. The results of this research can provide a decision-making basis for the high-quality development of the Daihai Basin and provide reference cases for the green development accounting of other basins.
