【摘要】 基于2010—2018年陕西省土地利用现状调查数据,采用土地利用动态度模型、土地利用变化幅度、单一和综合土地利用动态度、土地利用程度综合指数、土地利用结构多样性指数、优势度指数、均匀度指数模型定量分析2010—2018年陕西省土地利用动态变化情况。结果表明,2010—2018年陕西省耕地、草地和未利用土地面积呈减少趋势,未利用土地转化较明显;园地、林地、城镇村及工矿用地、交通运输用地和水域及水利建设用地均有不同幅度增加,林地增幅最为突出;2018年土地利用程度综合指数为232.25,土地利用程度相对较高;9年间土地利用年变化率为0.76%,土地利用变化较为缓慢。更多还原

【Abstract】 Based on the data of land use survey status in Shaanxi province from 2010 to 2018,land use dynamic degree model,land use change range,single and comprehensive land use dynamic degree,comprehensive land use degree index,land use structure diversity index,superiority index and the uniformity index model were used to quantitatively analyze the dynamic changes of land use in Shaanxi province. The results showed that the area of arable land,grassland and unused land were year by year decreased,the transform of unused land was obviously;Garden land,forest land,urban village and industrial and mining land,transportation industry land,water area and water conservancy construction land all had different rates of increase,the forest land increased most prominent;The comprehensive index of land use degree in 2018 was 232.25,and the degree of land use was relatively high;the annual change rate of land use in 9 a was 0.76%,and the change in land use was relatively slow.更多还原
