广西滨海区域景观格局分析及土地利用变化预测
Landscape pattern analysis and prediction of land-use change in the Guangxi coastal area
摘要
Abstract
The determination of landscape patterns of coastal wetlands has great significance in promoting the sustainable development of coastal regions.Spatiotemporal changes in landscape patterns in the coastal wetlands were analyzed using the moving window method.Three typical regions were extracted for variation tendency analysis of landscape patterns,and future trends in landscape evolution were predicted using the Land Change Modeler (LCM).The results showed that the areas of grassland,arbor plantation,and evergreen broad leaved shrub forest decreased,whereas that of industrial land increased.Changes in landscape heterogeneity and fragmentation were not obvious in the study region from 2000 to 2014.The comparison of landscape indices showed that the spatial distribution patterns of edge density were similar to that of the diversity index,indicating that regions with higher diversity also had higher edge density.Areas with higher diversity and edge density were located in Zhenzhu Bay,Maowei Sea,and the middle eastern portion of the study area.In addition,three typical regions exhibited similar patterns in which the diversity index decreased while the evenness index increased from 2000 to 2014.The number of patches and the area of coastal wetlands declined during this period.Results from the LCM revealed that areas of herbaceous wetland and mixed shrub and forested wetland have a declining tendency until 2020 because of their conversion to industrial land and residential land.Thus,the expansion of industrial land will be the main factor affecting land-use changes for these three typical regions.Zhenzhu Bay will experience the greatest level of land-use change,followed by Maowei Sea and Dandou Sea.In conclusion,changes in the regional landscape patterns resulted in decreased wetland quality;therefore,enhancing the protection of wetlands and limiting development of industrial land will be an effective way to maintain the integrity and security of the regional environment.关键词
