摘要:
通过2010~2016年济南市土地利用变化情况,研究土地利用和其生态服务价值,分析生态服务价值与社会经济因素的相关性。结果表明:济南市以耕地和城镇村及工矿用地为主;城镇村及工矿用地、交通运输用地面积有所增加,其他均减少;土地利用强度有上升趋势,但幅度较小;土地利用格局指数无明显波动;生态服务价值中耕地、水域、林地价值量最大;生态系统服务总价值及强度均逐年降低;生态服务价值强度指标与土地利用格局和人口无相关性;与土地与土地利用程度、GDP、GDP强度指标呈负相关;单位面积生态服务价值与土地利用程度呈弱相关、与GDP呈强相关、与GDP强度指标呈极强相关;人均生态服务价值与土地利用程度和GDP呈中等程度相关、与GDP强度指标呈极强相关。
Abstract:
Based on the land use change in Jinan from 2010 to 2016, this paper studied the dynamic change of land use and ecosystem service value, and analyzed the correlation between the ecological service value and socio-economic factors. The results showed that the land use types in Jinan were mainly arable land, urban villages, industrial land and mining land; the area of urban villages, industrial land, mining land, and transportation land are increased, while of other land use types reduced; the intensity of land use had an upward trend, but its increase was small; the land use pattern index was basically stable, without obvious fluctuation; the ecosystem services value of arable land, waters and forest land were highest; the value and the intensity of ecosystem services decreased year by year; the index of ecosystem service value intensity was not correlated with land use pattern and population, but it was negatively correlated with land use degree, GDP, GDP per unit area and GDP per capita; the index of ecosystem service value per unit area was weakly correlated with land use degree, but it was strongly correlated with GDP, and it was strongly correlated with GDP per unit area and GDP per capita. The per capita ecosystem service value was moderately correlated with land use and GDP, and it was strongly correlated with GDP per unit area and per capita GDP.
