摘要
利用2008年、2013年、2018年3期土地遥感解译数据,并结合GIS和RS技术、景观格局软件与地理探测器,探究汨罗江国家湿地公园景观格局时空演变特征及其影响因素。研究表明:(1)2008—2018年,汨罗江国家湿地公园建设用地面积持续增加,其他景观类型基本处于减少状态,其中耕地转移为建设用地趋势显著;(2)从斑块水平上看,斑块形状不规则,通达度较差,部分斑块被切割;从类型水平来看,景观空间异质性增强,破碎度加剧,形状趋于复杂;从景观水平来看,景观多样性不高,景观连接度下降,破碎化趋势显著;(3)地形、气候、水文等自然因素在汨罗江国家湿地公园景观格局演变中起基础性作用;经济发展水平、城市发展状况以及交通可达性对汨罗江国家湿地公园景观格局演变有重要影响,而政府政策对该湿地公园景观保护的支持力度有待加强;(4)汨罗江国家湿地公园开发与保护矛盾突出,有关各方要完善湿地公园评价标准与体系,科学规划建设湿地公园,运用多学科技术手段,综合管理湿地公园,从而实现国家湿地公园的可持续发展。
Using the data of 2008,2013 and 2018,we explored the evolution characteristics and influencing factors of the landscape pattern in Miluo River National Wetland Park combined with GIS and RS technology,landscape pattern software and Geodetector.Results showed that:(1)From 2008 to 2018,the construction land of Miluo River National Wetland Park continued to increase while other landscape types were basically in a state of decline.Among them,transfer of cultivated land to construction land had a significant trend.(2)From the level of plaque,the shape of plaque was irregular with some plaques cut and the accessibility was poor;at the perspective of type level,the landscape spatial heterogeneity was enhanced and the fragmentation was intensified.Thus,the shape of plaque was becoming more and more complex;from the overall landscape pattern,landscape diversity was at a relatively low level,landscape connectivity was decreasing,and the trend of fragmentation was significant.(3)Terrain,climate,hydrology and other natural factors played a fundamental role in the evolution of the landscape pattern of Miluo River National Wetland Park;the level of economic development and urban development as well as traffic accessibility had important effects on the landscape pattern evolution of the Park.Government policies should strengthen its support for the landscape protection of the wetland park.(4)Contradictions between development and protection of Miluo River National Wetland Park were apparent.All parties concerned should improve the evaluation standards and systems of wetland park to make scientific planning and construction.Multidisciplinary technical methods should be applied to integrated management so as to achieve the sustainable development of national wetland parks.
