摘要
本文以2009年和2019年甘谷县土地利用现状年度变更调查数据为基础,采用土地利用类型转入转出率、土地利用变化速度、土地利用动态度、土地利用类型变化程度和土地利用类型相对变化率等算法模型,对甘谷县土地利用10年间变化的特征进行了分析,并探讨了影响土地利用动态变化的各个因素.结果表明,甘谷县经济的快速发展和城镇化进程的加快,以及乡村振兴战略的实施,加快了土地利用类型的变化速度,但在甘谷县大力发展蔬菜、果椒和养殖等主导产业后,土地利用类型变化程度整体上放缓,土地利用结构进一步趋于合理化.
Abstract
The characteristics of land use changes in Gangu County in the past 10 years were analyzed based on the annual survey data of land use changes in the County in 2009 and 2019 in this paper by using such algorithm models as land use type transfer rate,land use change speed,land use dynamic attitude,land use type changes and land use type relative change rate,and the influencing factors were discussed.The results show that the speed of land use types changing has been increased with the rapid development of economy and the acceleration of urbanization in Gangu County,as well as the implemen-tation of rural revitalization strategy,while it has slowed down as a whole,and the land use structure has become more rational with the wide development of leading industries such as vegetables,fruits and pep-pers and aquaculture in the County.
