摘要:

基于条件价值法和随机效应logit模型对曹妃甸湿地生态系统支持服务价值进行了评估,并应用距离衰减模型对支持服务价值的空间演化和区域差异进行了研究。结果表明,在曹妃甸滨海湿地生态系统支持服务的构成要素中,湿地植被恢复对支持服务保护行为选择的影响效应最高,其次为湿地面积恢复影响效应,而生物多样性保护的影响效应最低;根据随机效应logit模型得到的2个滨海湿地生态系统支持服务保护方案每年可分别产生人均44.54元和46.57元的经济价值,该价值作为支持服务的“源价值”会随着与曹妃甸滨海湿地之间空间距离的增加而呈现出逐渐衰减的变化;不同空间范围下支持服务价值的衰减过程存在显著差异,空间范围越小,价值的衰减速率越快;支持服务价值依据衰减过程构建经济管辖范围,经济管辖范围与行政区边界不重合,同一行政区内的支持服务价值仍存在明显差异。

Abstract:

In this article, conditional value method and conditional logit model are applied to assess the supporting service value of coastal wetland ecosystem in Caofeidian District, and log-linear and exponential distance decay models are applied to analyzing the supporting value spatial evolution path and regional difference. The results show that wetland vegetation restoration has the greatest influence on the protection behavior choice of supporting service, followed by the effect of wetland area restoration and biodiversity protection. Two supporting service protection plans are obtained according to the regression results. The first one combines the options of ‘small-scale wetland area restoration, small-scale wetland vegetation restoration and small-scale biodiversity protection’ and generates a value of 44.54 Yuan per person per year. The second one combines the options of ‘small-scale wetland area restoration, large-scale wetland vegetation restoration and small-scale biodiversity protection’ and generates a value of 46.57 Yuan per person per year. The values are regard as the source value of the coastal wetland ecosystem supporting service and they gradually decay as the spatial distance from the investigation site increase. The decay processes of the supporting service value at different spatial scales are significantly different, the smaller the spatial scale is, the faster the decay rate is. Supporting service constructs economic jurisdictions according to the value decay processes. The economic jurisdictions do not coincide with the administrative boundaries. The supporting service value in the same administrative region also shows significant differences. Supporting service protection is considered well-being enhancing for the whole society, there exist some other factors affecting the value spatial differencing process besides the distance, such as the economic development level, the wetland resource endowment and the local natural conditions. Nevertheless, the results obtained in this article can provide meaningful reference for future coastal wetland ecosystem management and prove useful as an input to the ongoing debate concerning the future regional sustainable development and ecological civilization construction.
