Research on the Trade-off and Synergy Relationship of Ecosystem Services in Turpan City,China
In order to study the ecosystem services and trade-off synergistic relationships in Turpan City,the ecosystem service equivalent method,correlation analysis,hotspot analysis and cluster analysis were used to explore the characteristics of regional ecosystem service and trade-off and synergy,and to provide optimization suggestions based on service clusters.The results showed that:(1)The ecological service showed the characteristics of reduced loss,with a total loss of 191 million yuan.Grassland and unused land are the main land category providing ESV,followed by water area and cultivated land.(2)Ecosystem services show a reduced synergistic gain relationship year by year.Individual service hotspots account for the highest proportion and cultural service hotspots;among multiple hotspots,the 0 hotspots have the highest proportion and the 3 hotspots have the lowest proportion,and the distribution of hot spots in Turpan is relatively stable.(3)Ecosystem service clusters in Turpan City are divided into 5 categories,with wide ecological improvement area and low service level;ecological conservation areas have ecological service supply capacity;ecological fragile areas are weak and sensitive to external response;crop production capacity and nutrient supply capacity;ecological protection area has the least proportion,balanced service supply capacity,good ecological base and high importance of ecological protection.
