摘要
研究土地利用的演化特点,不仅可以确定其与自然、人文活动影响因子之间的联系,而且可以为我国的国土空间规划和生态文明建设提供一定的参考。本研究以佳木斯市为研究区,分析2008年、2014年、2020年佳木斯市土地利用变化及演变过程,并基于GeoSOS-FLUS模型模拟2026年、2038年佳木斯市土地利用情况,探讨佳木斯市未来土地利用变化特征。结果表明:2008至2014年佳木斯市耕地、草地、水体、不透水地面面积增加,森林、裸地、湿地面积减少。其中,草地面积动态度绝对值最大;2014年至2020年佳木斯市草地、水体、裸地、不透水地面面积增加,耕地、森林、湿地面积减少,其中裸地面积动态度绝对值最大;2008年至2020年佳木斯市耕地、草地、水体、不透水地地面面积增加,其中草地动态度绝对值最大。森林、裸地、湿地面积减少,其中湿地动态度绝对值最大;在2026年、2038年佳木斯市不透水地面面积持续增加,耕地、森林、湿地持续减少。本研究结果对合理利用土地资源,促进生态环境可持续发展具有一定的现实意义。
Studying the evolutionary characteristics of land use can not only determine the relationship between land use and natural and human activities, but also provide some reference for land space planning and ecological civilization construction in China. This study takes Jiamusi City as the study area, analyzes the land use change and evolution process of Jiamusi City in 2008, 2014 and 2020, and simulates the land use situation of Jiamusi City in 2026 and 2038 based on GeoSOS-FLUS model to discuss the characteristics of future land use change of Jiamusi City. The results show that from 2008 to 2014, the area of cultivated land, grassland, water body and impervious ground in Jiamusi increased, while the area of forest, bare land and wetland decreased. Among them, the absolute value of grassland area dynamic degree is the largest. From 2014 to 2020, the area of grassland, water body, bare land and impervious ground in Jiamusi City will increase, while the area of cultivated land, forest and wetland will decrease, among which the absolute value of the dynamic degree of bare land area is the largest. From 2008 to 2020, the area of cultivated land, grassland, water body and impervious land in Jiamusi City will increase, among which the absolute value of grassland dynamic degree is the largest. The area of forest, bare land and wetland decreased, and the absolute value of wetland dynamic degree was the largest. In 2026 and 2038, the impervious surface area of Jiamusi City will continue to increase, and the cultivated land, forests and wetlands will continue to decrease. The results of this study have certain practical significance for rational utilization of land resources and promotion of sustainable development of ecological environment.
