摘要
为研究吉林西部湿地变化规律,解析生态地质环境因子对吉林西部湿地演化的影响,选取吉林西部典型区域,采用CBERS-2和Landsat-8 OL所揭示的两期湿地数据,通过地学信息图谱,结合湿地分布密集信息图、相对变化率量化分布现状和变化趋势,以高程、气候、人口等数据为参照,研究湿地动态变化与其环境之间关系。研究结果表明:2017年研究区内水稻田面积最多,研究区内北侧湿地分布密度等级普遍较高;2007年至2017年湿地总面积呈现增加趋势;新构造运动控制了湿地发育,降水成为影响近10年来湿地变化的主要因素。
In order to study the transformation law of wetland in western Jilin and analyze the impact of eco-geological environment factors on the evolution of wetland, a representative region of western Jilin is selected and the two-stage wetland data revealed by CBERS- 2 and Landsat- 8 OL are used. Through the geo-information atlas, combining with intensive infographic of wetland distribution and the distribution status and variation trend of quantified relative change rate, elevation, climate and population data, the relationship between wetland dynamic change and environment is studied. The results show that paddy fields cover the largest area in study area in 2007 and the distribution density of wetlands on the north side of the study area is generally high. The total wetland area shows an increasing trend, the Neotectonic movement controls wetland development and precipitation becomes the main factor which affected wetland changes in the past 10 years.
