1990~2020年嫩江流域土地利用变化分析

Analysis of Land Use Change in the Nenjiang River Basin from 1990 to 2020

摘要: 嫩江流域作为我国东北地区一个相对完整、面积广阔的流域，不仅维系着流域内千万人口的生计，而且为全国提供了大量的商品粮是国家重要的粮食产出地，具有举足轻重的地位。本文以嫩江流域为研究对象，利用ArcGIS软件，将嫩江流域近三十年土地利用的变化情况进行制图，输出土地利用数据进行对比分析并应用地理探测器分析土地利用变化的驱动因素。掌握嫩江流域1990~2020年的土地利用变化规律，旨在为嫩江流域土地利用规划的制定和可持续发展提供依据。

Abstract: As a relatively complete and extensive river basin in Northeast China, the Nenjiang River Basin not only maintains the livelihood of tens of millions of people in the basin, but also provides a large amount of commercial grain for the whole country, and is an important grain producing area of the country, which has a pivotal position. In this paper, the Nenjiang River Basin was taken as the research object, and ArcGIS software was used to map the land use changes in the Nenjiang River Basin in the past 30 years, and the land use data were output for comparative analysis, and the driving factors of land use change were analyzed by using geographic detectors. To grasp the law of land use change in the Nenjiang River Basin from 1990 to 2020. The purpose of this study is to provide a basis for the formulation and sustainable development of land use planning in the Nenjiang River Basin.
