Ecosystem Service Value Evaluation of Saline—Alkali Land Development in the Yellow River Delta—The Example of the Huanghe Island

Saline–alkali land is an important resource with high development potential and ecological product ecosystem service value (ESV). It of great significance for rational protection saline–alkali resources to carry out research on the evaluation methods ESV scientifically quantify development. Taking typical in Yellow River Delta Huanghe Island China as example, this constructed index system from perspective functional containing three first-level indicators such economic value, four second-level supply service, eight lowest-level food production. also considered production operation costs evaluated using economics method. The results showed that CNY 133.586 million, unit area 50,200 CNY/hm2, which a relatively value. Among them, was highest, accounting more than half. In recent years, has produced but due weak background conditions low vegetation coverage, regulation support values are low, cultural still be explored, there social This can provide references scientific basis utilization Island.
