摘要
分析土地利用与生态系统服务价值的关系,可以为土地规划和资源可持续利用提供科学依据。以甘肃省张掖市甘州区为例,研究了2010—2016年该区土地利用变化情况,同时建立与生态系统服务价值的空间联系,以期为缓和该地经济发展与生态环境之间的矛盾提供科学依据。结果发现,甘州区土地利用随着城市化进程的推进变化显著,其中建设用地变化率最大,主要由耕地和水域转入。未利用地主要转化为耕地,面积逐年下降。耕地面积总体有所增加,呈先增后减的特点。林地、草地、园地和水域面积变化幅度较小,且均呈下降趋势;土地利用变化对生态系统服务价值影响强烈,土地生态系统服务价值总体逐渐降低,主要由建设用地面积快速增加和水域面积减少所致。因此,政府应合理利用土地,协调好经济发展与环境的关系。
Analysis of the relationship between land use and ecosystem service value can provide a scientific basis for land planning and sustainable resource use.Ganzhou District of Zhangye City,Gansu Province was taken as an example to research land use change from 2010 to 2016,at the same time,using the data obtained to establish a spatial connection between land use change and ecosystem service value,in order to provide a scientific basis for easing the contradiction between economic development and ecological environment.Research indicated that with the advancement of urbanization,land use in Ganzhou District of Zhangye City has changed significantly,the construction rate was the largest,transferred to land was mainly cultivated land and waters.Unutilized land was mainly converted into cultivated land,and the area was decreasing year by year.The total area of cultivated land has increased,presenting the characteristics of increasing first and then decreasing.The range of change of forest,grassland,garden and water area were small,and all showed a downward trend.Land use change had a strong impact on the value of ecosystem services,the value of land ecosystem services was overall reduction,the main factors were the increase of construction land area and the reduction of water area.Therefore,the government should make rational use of land and coordinate the relationship between economic development and the environment.
