摘要
参照千年生态系统评估的生态系统服务分类体系,以及生态系统服务类别间的相互作用,将辽宁近海海洋生态系统服务归纳为资源供给、环境调节和人文社会三大类共10项,并采用生态经济学的理论和研究方法,对辽宁近海海洋生态系统服务价值进行测评。结果表明:①2007年辽宁近海海洋生态系统服务总价值为710.35×108元,相当于2007年辽宁省GDP的6.44%。平均单位面积海域的生态服务价值为203.02×104元/km2;②在辽宁近海海洋生态系统服务总价值中,资源供给服务、环境调节服务、人文社会服务价值分别占33.18%、15.04%和51.78%。从所评价的10项海域生态服务的价值量大小看,依次为旅游娱乐价值>食品供给价值>水质净化调节价值>空气质量调节价值>干扰调节价值>气体调节价值>科研文化价值>基因资源供给价值>有害生物与疾病的生物调节与控制价值>原材料供给价值。
Offshore marine ecosystem services of Liaoning province can be basically categorized as three groups of resource supply, environment adjustment and humanities society encompassing ten items on the basis of the ecosystem services classification system from the millennium ecosystem assessment and accounting for the interaction among different ecosystem services categories. In the present research, the authors performed a study on the assessment of offshore marine ecosystem value and services of Liaoning Province based on theories and methods of ecological economics. Results indicated that first, the total value of the offshore marine ecosystem services of Liaoning Province was roughly 710.35 × 10^8Yuan in 2007, which is equal to 6.44% of the gross domestic product of the province in the same year, with showing a average value of marine ecosystem services per unit sea area of 203.02 × 10^4Yuan/km^2. It seems that the estimation was little smaller than the actual service value of Liaoning offshore marine ecosystems. However, it still showed a tremendous value the ecosystem provides. Second, resource supply value, environmental adjustment value and humanities society value accounted for 33.18%, 15.04% and 51.78% of the total value of the marine ecosystem services, respectively. The authors ordered the magnitudes of the value of marine ecosystem services of selected ten items subsequently, with showing that tourism and entertainment services have the highest value, followed by food provision services, water quality purification and regulation services, air quality regulation services, disturbance regulation services, gas regulation services, scientific and culture services, gene resources provision services, harmful organism and disease control services, and raw material provision services. It was suggested that the sea fishery and coastal tourism in Liaoning have been substantially developed. We should place emphasis on establishing standard laws and regulations and making them work effectively, efficiently and constantly, obviating the trend in decline of tourism and entertainment services and food provision services value. It also showed that Liaoning offshore marine ecosystems can greatly contribute to the growth of local economy, create a series of social benefits as well as indispensible ecological benefits.
