Coastal wetland ecosystem evaluation in Guangdong Province by eliminating the double counting
摘要
Abstract
Ecosystem service value assessment sarevital in ecological economics as well as environmental eco-nomics, and coastal wet lands are an important component of an ecosystem. To better understand the compo-nents and characteristics of coastal wetlands and consequently evaluate its finial ecosystem service values, the coastal wetlands in Guangdong Province was investigated and the 11 kinds of final services with eliminating the double counting were determined. The 11 kinds of final services in Guangdong Province were selected based on literature and field survey, and which were used to calculate the total value for the coastal wetlands in the study area. Subsequently, the evaluation system and methods of the final services were established and select-ed, such as market method, replacement cost method, field survey method, and other environmental economic evaluation methods. Results showed that the total value of coastal wetland ecosystem services in Guangdong Province in 2013 was 664.1 ×108 RMB yuan with an average value of 8.1 RMB yuan·m-2·a-1. The greatest a-mong the indexes was the food supply service with 488.0 ×108 RMB yuan, accounting for 73.48% of the total value. The second largest index was recreation (124.1×108 RMB yuan, 18.7%) followed by wind power supply (16.7×108 RMB yuan, 2.52%), carbon sequestration (11.4×108 RMB yuan, 1.71%), water purification (11.3× 108 RMB yuan, 1.70%), ocean shipping (4.3×108 RMB yuan, 0.64%), climate regulation (3.6×108 RMB yuan, 0.54%), water supply (2.3 ×108 RMB yuan, 0.35%), wave reduction and coastal protection (1.4 ×108 RMB yuan, 0.21%), raw material supply (1.0×108 RMB yuan, 0.15%), and scientific research (0.1×108 RMB yuan,0.01%). This indicated that coastal wetlands could not only have enormous economic, ecological, and social benefits, but could also play an irreplaceable role in the preservation of coastal ecological security and the de-velopment of the national economy in Guangdong Province or even in South China.关键词
