松花江干流水域岸线生态时空演变及驱动因子分析

Spatiotemporal Evolution and Driving Factor Analysis of Shoreline Ecology in Songhua River Mainstream Waters

河岸带是水陆交错带,岸线资源十分珍贵,其质量关系到陆地及河流两者的生态状况。为探究自然因素和人类活动对松花江水域岸线生态格局演变产生的影响以及阶段性规律,以松花江河道管理范围的岸线空间演变为主线,以GIS作为基础技术,利用土地转移、空间计算、统计分析等数据处理方法,对松花江干流佳木斯段2014—2022年土地转移状况、空间自相关特征、驱动因子贡献进行研究。

The riparian zone is a transitional zone between water and land,the shoreline resources are very precious and their quality play an important role in the ecological status of water and land.In order to explore the influence of natural factors and human activities on the evolution of the ecological pattern of the Songhua River shoreline and the stage law,the spatial evolution of the shoreline of the Songhua River management scope is considered as the main line,and the GIS method is used as the basic technology.The data processing methods such as land transfer,spatial calculation and statistical analysis are used to study the land transfer status,spatial autocorrelation characteristics and driving factors of the Jiamusi section of the main stream of the Songhua River from 2014 to 2022.
