【摘要】：生態(tài)系統(tǒng)服務(wù)價值研究是目前生態(tài)學(xué)研究的熱點(diǎn)之一,海島生態(tài)系統(tǒng)的特殊性令其更易受人類活動和環(huán)境變化的影響。文章在海島生態(tài)系統(tǒng)服務(wù)價值當(dāng)量修訂的基礎(chǔ)上,對典型海島金塘島1986—2014年的生態(tài)系統(tǒng)服務(wù)價值進(jìn)行評估,分析了金塘島近30年來生態(tài)系統(tǒng)服務(wù)價值的時空動態(tài)變化。結(jié)果表明:城鎮(zhèn)生態(tài)系統(tǒng)面積持續(xù)增加,其他生態(tài)系統(tǒng)類型面積不同程度減少,減少的生態(tài)系統(tǒng)類型大多數(shù)轉(zhuǎn)化為城鎮(zhèn)。1986—2014年金塘島的生態(tài)系統(tǒng)服務(wù)總價值呈下降趨勢,共減少了1.08億元,減少了30.23%,其中濕地與森林的生態(tài)系統(tǒng)服務(wù)價值量減少最多,城鎮(zhèn)的價值變化率最大�？臻g上表現(xiàn)為價值極低區(qū)域沿著人類活動方向呈現(xiàn)急劇擴(kuò)大趨勢。生態(tài)系統(tǒng)提供的產(chǎn)品與服務(wù)在數(shù)量和質(zhì)量上逐步下降,不利于海島的可持續(xù)發(fā)展。該研究為海島地區(qū)生態(tài)系統(tǒng)服務(wù)價值當(dāng)量修訂提供參考,同時對轉(zhuǎn)變海島經(jīng)濟(jì)發(fā)展方式,促進(jìn)海島可持續(xù)發(fā)展提供基礎(chǔ)信息與決策依據(jù)。
[Abstract]:The study of ecosystem service value is one of the hotspots in ecological research at present. The particularity of island ecosystem makes it more vulnerable to the influence of human activities and environmental changes. Based on the revision of service value equivalent of island ecosystem, this paper evaluates the ecosystem service value of Jintang Island from 1986 to 2014, and analyzes the temporal and spatial dynamic changes of ecosystem service value in Jintang Island in the past 30 years. The results showed that the area of urban ecosystem continued to increase and the area of other ecosystem types decreased to varying degrees. Most of the reduced ecosystem types were converted into the total value of ecosystem services of Jintang Island from 1986 to 2014. The value of ecosystem services of wetland and forest decreased the most, and the value of urban value changed the most. In space, the extremely low value region shows a trend of rapid expansion along the direction of human activities. The quantity and quality of the products and services provided by the ecosystem are decreasing gradually, which is not conducive to the sustainable development of the islands. The study provides a reference for the revision of the ecosystem service value equivalent in the island area, and provides the basic information and decision basis for the transformation of the island economic development mode and the promotion of the island sustainable development.
