Ecological Effects of Surface Water Evolution in the Yellow River Delta

With the ecological protection and high-quality development of Yellow River Basin rising to China’s national strategy, Delta is facing a historic opportunity, surface water problems in this region are becoming more severe. Owing dual effects swing River’s channel human activities, an evolving state. Consequently, it important pay attention ecosystem response caused by evolution for Delta. Drawing on ecological, economic, network analysis, study, service landscape from 1986 2019 explored using remote sensing socioeconomic data. The results as follows: (1) has evolved significantly last 35 years. Artificial accounted dominant proportion total water, composition tended be remarkably heterogeneous. (2) services delta increased during study period. improved varying degrees except sedimentary land reclamation. Tourism, materials production, supply became leading functions cultural rose rapidly, share regulatory shrank significantly. (3) had evident impact pattern Delta, which was manifested physical cutting spatial attraction. This demonstrates comprehensive effect protective constraints, attraction, exclusion regional types. have certain guiding significance management resources also provide information region.
