摘要

[目的] 通过研究青海省河湟谷地1980—2020年来的土地利用变化规律及成因，为当地土地资源管理提供科学依据。[方法] 基于1980

1990

2000

2010

2020年5期土地利用资料，应用土地利用转移矩阵、变化量分析、综合动态度及冷热点分析等方法，对河湟谷地近40年来的土地利用数量与空间变化规律及成因进行分析。[结果] ①1980—1990年河湟谷地以草地增加为主，1990—2000年以耕地和未利用地增加为主，2000—2010年以草地增加为主，2010—2020年各地类数量变化不明显。②1980—1990年未利用地向草地转化主要发生在西南部及北部，2000—2010年耕地向草地转化主要发生在中部。③河湟谷地土地利用变化热点区主要分布在贵德县、尖扎县、同仁市、循化县、民和县、化隆县、门源县和平安区。冷点区主要分布在大通县、门源县、乐都区和同仁市。[结论] 国家政策、地方政策等因素导致了土地利用变化的时空差异，对于不同地区应因地制宜、有侧重地选择研究方法，才能优化土地利用结构，实现城乡振兴。

Abstract

[Objective] The law and causes of land use dynamic changes in Hehuang Valley of Qinghai Province from 1980 to 2020 were studied in order to provide a scientific basis for land resource management. [Methods] Land use data (1980

1990

2000

2010

and 2020)

land use transfer matrix

change analysis

comprehensive dynamic attitude

and cold and hot spot analysis were used to analyze the quantity and spatial changes of land use in Hehuang Valley during 1980—2020. [Results] ① The main land use changes were the increase of grassland from 1980 to 1990 and from 2000 to 2010

and the increase in cropland and unused land from 1990 to 2000. However

there were no significant changes in the number of different land use regions from 2010 to 2020. ② The conversion of unused land to grassland occurred mainly in the southwest and north from 1980 to 1990. From 2000 to 2010

the conversion of cultivated land to grassland mainly occurred in the central region. ③ Hot spots of land use change in Hehuang Valley were mainly located in Guide

Jianzha

Xunhua

Minhe

Hualong

Menyuan counties

Tongren City

and Pingan District. The cold spots were mainly located in Datong

Menyuan County

Ledu District

and Tongren City. [Conclusion] National and local policies and other factors have led to spatial and temporal differences in land use changes. Only by selecting research methods according to local conditions and focusing on different areas

can we optimize land use structure and realize the revitalization of urban and rural areas.
