辽河三角洲盘锦湿地景观格局变化的生态系统服务价值响应

Response of Ecosystem Service Value to Wetland Landscape Pattern Change in Panjin Region of Liaohe Delta

利用1990～2010年5期卫星遥感影像监测了辽河三角洲盘锦湿地景观格局变化特征,并采用市场价值法、碳税法、影子工程法、当量因子法等多种评估方法,对辽河三角洲盘锦湿地景观格局变化的生态系统服务功能价值响应进行深入研究。结果表明:芦苇湿地、河口水域和稻田是辽河三角洲湿地景观的最主要组分,芦苇湿地、滩涂等自然湿地景观面积的萎缩,稻田、养殖池塘等人工湿地景观面积的扩大是湿地景观格局变化的主要特征。辽河三角洲盘锦湿地景观格局变化导致2010年湿地生态系统服务功能价值比1990年减少8.39亿元。辽河三角洲湿地景观格局变化导致生态系统服务功能中的污染物净化功能价值损失6.64亿元,物质生产功能价值增加2.83亿元。物种保护功能价值和休闲娱乐功能价值分别损失2.23亿元和2.06亿元,而气候调节功能价值和水文调节功能价值对湿地景观格局变化响应不明显。

In this paper, the change of wetland landscape pattern in Panjin region of Liaohe delta was surveyed by using the interpreted data of five remote sensing images from 1990 to 2010. Some methods including market value, engineer value, value index were employed to assess response of the ecosystem service value to wetland landscape pattern change. The result showed that reef swamp, rice field and coastal water field were three main components of the wetland landscape in Panjin region of Liaohe delta, and natural landscape such as reef swamp, paddy field were reduced, while rice field and pound which were man made were expanded. The ecosystem service value was response to the wetland landscape pattern changing with 8.39 × 10 8RMB decreased from 1990 to 2010. The wetland landscape pattern changing leaded 6.64 × 10 8RMB purifying function, 2.23 × 10 8RMB habituating function and 2.06 × 10 8RMB leisure function lost,while only obtained 2.83× 10 8RMB materials and food product function. And climate contoll function and hydrological controll function were not response to wetland landscape pattern changing in Panjin region ofLiaohe Delt obviously.
