摘要

摘要: 气候变化和人类活动的加剧,使地球上重要的生态系统——湿地被不断侵占与破坏,当前建立湿地退化的科学评估方法十分迫切且必要。基于区域生态风险理论,从胁迫度和退化度2个角度建立了包含22项指标的湿地退化多指标评估体系,并对天津市1990—2015年湿地退化风险进行评估。结果表明:由于胁迫度的波动变化和湿地自身退化度的上升,天津市1990—2015年湿地退化风险呈先下降后上升的趋势,2015年的退化风险较1990年增加了10.08%,且原本湿地退化风险较低的区域呈现风险快速上升的现象。亟待出台更严格的相关政策和建立更完善的管理制度,以加强天津市湿地的保护与恢复。

Abstract: Due to the acceleration of the climate change and human activities, the wetlands, which are important ecosystem on the earth, are continuously appropriated, damaged and even disappearing. It is thus very urgent and necessary to establish a reliable evaluation model for the wetlands degradation. Based on the theory of regional ecological risks, a multi-index evaluation system including 22 indexes was established from the two aspects of stress degree and degradation degree, and the risks of wetland degradation in Tianjin from 1990 to 2015 was assessed. The results showed that the risk of wetland degradation in Tianjin City showed a trend of decreasing first and then increasing due to the fluctuation change of stress degree and the increase of degradation degree of the wetland itself. The value of degradation risk in 2015 increased by 10.08% compared to 1990. And the risk value of the areas with originally low risk of wetland degradation presented a phenomenon of rapid increase of risk. Therefore, it is urgent to formulate more strict policies and build up a better management system to strengthen the protection and restoration of wetlands in Tianjin City.
