【摘要】：为阐明水位和植被生长状况的季节变化对湖泊湿地景观格局所产生的影响,以浅水通江湖泊安徽菜子湖为例,选取相邻年份不同月份的SPOT-5影像,基于RS/GIS解译得到湖泊湿地景观图,统计分析不同季节的湿地景观结构及其相互转化,并利用Fragstats景观格局分析软件从景观和类型2个层次探讨不同季节的湿地景观格局指数变化。结果表明,菜子湖湿地景观以水体为主,受到湖泊水位和植被生长状况影响,湿地景观结构发生明显的季节变化;湖泊湿地景观的季节变化是以不同类型之间的可逆转移实现的;随着湿地景观结构的改变,类型和景观2个层次的景观格局指数也发生季节性波动。该研究可为长时间序列浅水型湖泊湿地景观变化研究中的遥感影像选取提供科学依据。
[Abstract]:In order to elucidate the influence of seasonal variation of water level and vegetation growth on the landscape pattern of lake wetland, the SPOT-5 images of adjacent years and different months were selected, taking Chaizi Lake of Anhui Province, a shallow Tongjiang lake, as an example. Based on RS / GIS interpretation, the lake wetland landscape map was obtained, and the wetland landscape structure and its mutual transformation in different seasons were statistically analyzed, and the changes of wetland landscape pattern index in different seasons were discussed by using Fragstats landscape pattern analysis software from two levels of landscape and type. The results showed that the wetland landscape of Caizi Lake was dominated by water body, affected by lake water level and vegetation growth, and the wetland landscape structure had obvious seasonal changes. The seasonal change of lake wetland landscape is realized by reversible transfer between different types, and with the change of wetland landscape structure, the landscape pattern index of type and landscape level also fluctuates seasonally. This study can provide scientific basis for the selection of remote sensing images in the study of wetland landscape change of shallow lakes in a long time series.
