摘要:

为了明确白银市土地利用状况与生态系统服务价值之间的关系,进一步确定白银市各土地利用类型对生态系统的影响程度。本研究选择当量因子法评价白银市2009—2017年土地利用状况、生态系统服务价值以及两者之间的关系。结果表明:(1)2009—2017年,白银市生态系统服务价值总量从56.75亿元下降到56.49亿元,总体呈下降趋势,各项生态系统功能和生态系统服务都呈下降趋势;草地生态系统服务价值减少了2549.18万元,减少最多,人口对生态系统负荷呈减轻趋势;(2)白银市土地利用类型对生态系统服务价值具有较大的影响,主要受建设用地增加较多,草地和林地面积减少影响较大,在以后的发展中,要从保护生态用地、挖掘存量建设用地方面,探索出一条生态优先、绿色发展的新路子。

Abstract:

To clarify the relationship between land use status and ecosystem service value in Baiyin City, and further determine the impact of land use types on the ecosystem, in the study, the equivalent factor method was used to evaluate the land use status, ecosystem service value and the relationship between them in Baiyin City from 2009 to 2017. The results showed that: (1) from 2009 to 2017, the total value of ecosystem services decreased from 5.675 billion yuan to 5.649 billion yuan in Baiyin City, the general trend was downward, all ecosystem functions and ecosystem services were also downward; the value of grassland ecosystem services had the largest reduction and decreased by 25.4918 million yuan, and the population load on the ecosystem showed a downward trend; (2) land use types had great impacts on ecosystem service value in Baiyin City, it was mainly due to the increase of construction land and the decrease of grassland and woodland area. In future development, we should explore the ecological development from the aspects of protecting ecological land and excavating the stock of construction land.

Key words: land use type, ecosystem service value, value equivalent, land use dynamic degree, sensitivity, Baiyin City
