Ecosystem Services Valuation of Lakeside Wetland Park beside Chaohu Lake in China

Abstract

Abstract:Wetland ecosystems are one of the three great ecosystems on Earth. With a deepening of research on wetland ecosystems, researchers have paid more and more attention to wetland ecosystem services such as flood mitigation, climate control, pollution prevention, soil-erosion prevention, biodiversity maintenance, and bio-productivity protection. This study focuses on a lakeside wetland ecosystem in Hefei, a city in central China, and estimates the value of ecosystem services such as material production, air purification, water conservation, biodiversity, recreation, species conservation, education and scientific research. We adopted the market value method, carbon tax method, afforestation cost method, shadow engineering method and contingent value method (CVM) using questionnaire survey data during the study period. The results show that the total value of the ecosystem services of Lakeside Wetland Park was 144 million CNY in 2015. Among these services, the value of society service is the maximum at 91.73 million CNY, followed by ecological service and material production service (42.23 million CNY and 10.43 billion CNY in 2015 respectively). When considering wetland ecosystems for economic development, other services must be considered in addition to material production to obtain a longer-term economic value. This research reveals that there is scope for more comprehensive and integrated model development, including multiple wetland ecosystem services and appropriate handling of wetland ecosystem management impacts.

LUCC and Ecosystem Service Value Assessment for Wetlands: A Case Study in Nansi Lake, China

“…Human activities interact with the surrounding environment and form a complex social-ecological system, which affects and directs the flow of ES. As one of the three most significant ecosystems, the wetland ecosystem is known as the "kidney" [2] of the earth because of its ecological regulating functions and valuable natural resources. The ecosystem services value (ESV) of wetland is among the highest of any ecosystem assessed [1,3].…”

“…However, with the rapid population growth and excessive resource consumption, the stability and biodiversity of wetland ecosystem were seriously damaged [6,10,11]. Increasing environmental and resource problems resulted in the degradation of wetlands, restricting the sustainable development of regional economy and society [2,12]. In China, the wetland area has been reduced by approximately 33% in the past 30 years, and 40% of the key protected wetlands are facing severe threat of degradation [13,14].…”

National Large-Scale Wetland Creation in Agricultural Areas—Potential versus Realized Effects on Nutrient Transports

“…However, the impacts on biodiversity and on phosphorus transports were later added as important benefits obtained through wetland creation in agricultural areas [5,8,9]. There is also an increasing awareness worldwide that wetlands provide a multitude of ecosystem services [10][11][12]. Different national subsidy programs have been used in Sweden to provide incentives to farmers to create wetlands on their land [5,13].…”

Ecosystem Services and Perception of Water Quality of Lake Barombi Kotto, Cameroon

“…Lakes carryout a wide range of ecosystem services which can be grouped into four categories: Provisioning, Regulatory, Cultural and Aesthetic services (MEA, 2005;Li and Gao, 2016) and they are mostly valued for these services by the community. Human-dominated ecosystems encompass a wide range of human activities such as agriculture, mining, urbanization and industrialization.…”
