摘要
以上海海湾国家森林公园为例,采用土地动态和景观格局分析,运用生态系统服务价值当量法,定量地分析2000-2018 年土地利用变化特征,同时对景观格局的演变和生态系统服务价值进行评估研究,探讨土地利用变化、景观格局和生态系统服务价值三者之间的关联性.结果表明,研究区在2000-2018 年土地利用类型发生快速变化,植被、道路、农田3 种景观类型的面积波动较大,林地和道路快速增加,农田快速减少,呈现"两多一少"的变化趋势,占优势的景观基质由农田斑块类型转变为林地斑块类型;研究区的景观类型从开始的破碎化、不均匀的状态逐步向均衡化发展;总ESV从2000年的8659.51 万元增加到2018 年的13412.42 万元,增加了54.89%,其中水体和植被是提供生态系统服务价值的主要地类,调节服务价值量相对于其他三项服务类型处于明显较高的水平;斑块数量的不断增加,林地和水体等优势景观类型面积的增加,景观类型形状多样化、均衡化使研究区的生态系统服务价值不断增加,生态系统服务价值变化强度和土地利用强度之间存在较强的正相关关系.
Abstract
The characteristics of land use change in Shanghai Bay National Forest Park from 2000 to 2018 were quantitatively analyzed by using the land dynamics and landscape pattern analysis,and the e-cosystem service value equivalent method.The evolution of the landscape pattern and the ecosystem serv-ice value were evaluated,and the correlation between land use change,landscape pattern and ecosystem service value was discussed.The results showed that the land use types in the study area changed rapidly from 2000 to 2018,with significant fluctuations in the area of vegetation,roads,and farmland.Forest land and roads increased rapidly,while farmland decreased rapidly,showing a trend of"two more and one less".The dominant landscape matrix shifted from farmland patch type to forest patch type.The landscape types gradually developed from fragmented and uneven state to balanced state.The total ESV increased from 86.595 1 million yuan in 2000 to 13.412 42 million yuan in 2018,with an increase of 54.89%.Water bodies and vegetation were the main land types providing ecosystem service value,and the value of regulating service value was at a significantly higher level compared with the other three serv-ice types.The increasing number of patches,the increasing area of dominant landscape types such as for-est land and water body,the diversification and equalization of landscape types made the value of ecosys-tem services in the study area increase continuously.There was a strong positive correlation between the intensity of changes in ecosystem service value and the intensity of land use.
