摘要
在生态服务功能传统评价方法的基础上,拓展了生态服务功能的评价流程,即增添了生态服务的时空尺度与利益关系分析。研究了山东省长岛县生态服务价值的变化趋势、生态服务价值的空间表现、生态价值的社会群体利益关系。结果表明:1994年～2003年,长岛县生态服务价值总体呈现出增—减—增的趋势,1999年生态服务价值降到最低值74523万元,2003年上升到最大值101886万元;分析并计算长岛县生态系统的生物生产性服务、娱乐功能、自然保护价值,这些服务功能表现出明显的空间差异性,即生物生产服务功能仅对长岛区域至关重要,娱乐功能不仅体现在长岛区域,更多体现在全国范围,自然保护价值体现于全国乃至全球范围;分析了不同参与者在获取生态服务方面的差异及参与者之间的生态利益关系,不同的参与者在其空间范围中取得不同的生态服务;生态服务功能的时空分析、利益关系分析是生态管理部门制定科学决策的基础。
The valuation of ecosystem services is highlighted in many eco-economics researches. However, there is relatively little elaboration of the temporal and spatial scales at which ecosystem services are given. Based on the new methods of evaluating ecosystem services, the framework to valuate ecosystem services is enhanced, i. e. to be added the spatial, temporal scales and benefit analysis on ecosystem services and benefit characters. The ecological services in Changdao island, Shandong province, are analyzed and the resuhs are as follows ： the changeable trend of ecosystem service values from 1994-2003 fluctuates and the aquatic product, food, fruit scales, namely, the values trough is 7. 4523 × 10^8 ￥ in 1999,wave crest 1. 018186 × 10^9 ￥in 2003 ; the values of , nature conservation and recreation are calculated, their services are characterized with spatial of aquatic product, food and fruit are only important to people in Changdao island, recreation value to not only Changdao island but also provincial or national scale, nature conservation to national and international scale. Our analysis shows that communities or people at different spatial scales can have different interests in ecosystem services. The valuation of ecosystem services based on temporal, spatial and benefit characters supports the decisionsmaking by departments of ecosystem management.
