摘要
本文以河北段大运河主河道河岸分别向外侧扩展2 km范围内的区域作为研究对象,对土地利用变化情况进行三种定量分析,即土地利用结构分析、土地利用多样化分析和土地利用变化程度分析。结果表明,研究期内土地利用结构中耕地始终是主要地类;土地利用多样性保持相对稳定,处于中等偏低水平;各地类土地利用动态变化程度相差较大。土地利用变化较快的有裸地、盐碱地、草地、水域、园地、林地等,面积逐年减少,其次是城镇村、交通道路、采矿用地、耕地、风景名胜及特殊用地等,面积逐年增加。
In this paper,the areas of the main channel of the Grand Canal in Hebei section are extended to the outside within 2 km,respectively,as the research objects,and three types of quantitative analysis of land use changes are performed,namely land use structure analysis,land use diversification analysis and land use change degree analysis.The results show that the cultivated land is always the main land type in the land use structure during the study period;the land use diversity remains relatively stable and at a moderately low level;the degree of dynamic change in land use varies greatly from place to place.The areas of land use that change rapidly are bare land,saline-alkali land,grassland,waters,garden land,forest land,etc.,the area of which is decreasing year by year,followed by urban villages,transportation roads,mining land,cultivated land,scenic spots and special land,etc.,and the area is increasing year by year.
