摘要
随着城市化进程的发展,城镇乡村都面临着建设用地不断扩张的局势,环境和生态系统受到了一定的威胁。通过对土地利用景观格局评估能够充分反映人类对区域环境改变的强弱和规律。以天津市蓟州区为例,选取1998年、2008年、2018年三个研究节点的遥感影像等数据,利用动态度模型、高程分析、监督分类、克里金插值、高程tin分析等多种模块,对蓟州区20年来土地利用变化特征和空间分异特征进行量化评估,结合评价结果分析总结蓟州区景观格局的总体规律和不足,提出需求与供给协调发展、生态保护优先、整体与类型流转、平衡绿地分布等优化策略。
With the development of urbanization,urban and rural areas are facing the situation of continuous expansion of construction land,resulting in a certain threat to the environment and ecosystem.Through the analysis on the landscape pattern of land utilization,we can fully reflect the strength and law of human changes to the regional environment.Taking Jizhou District of Tianjin as an example,this paper selects the remote sensing image and other data of three research nodes in 1998,2008 and 2018,and conducts quantitative evaluation on the land utilization characteristics and spatial differentiation in Jizhou District in the past 20 years with several modules,including dynamic degree model,elevation analysis,supervised classification,Kriging interpolation,elevation tin analysis,and so on.Then combined with the evaluation results,this paper analyzes and summarizes the overall laws and deficiencies of landscape pattern in Jizhou District,and puts forward optimization strategies,such as coordinated development of demand and supply,priority of ecological protection,overall and type circulation,balance of green space distribution,and so on.
