摘要

[目的] 通过分析流域的土地利用变化对流域内各个自然过程生态服务价值的影响，为流域土地资源的合理利用和流域生态安全保护提供科学依据。[方法] 基于土地利用转型变化，分析1980-2015年人类活动影响下的甬江流域土地利用变化及其生态服务价值变化。[结果] ①甬江流域土地利用变化以耕地的减少与建设用地的增加为主要特点，且土地利用程度不断上升。土地利用类型之间发生复杂的相互转化，转移面积最大的是耕地转向建设用地。②35 a间，甬江流域土地综合利用动态度为0.42%。建设用地土地利用单一动态度最大，耕地面积减小幅度最大。③甬江流域生态服务在时间层面上，总价值先增大后减小，在1995年之前不断增加，但在之后不断减少。④在空间层面上总体呈现出由西南向东北逐渐变低的趋势。[结论] 甬江流域土地利用转型剧烈，土地利用的快速变化加剧了生态系统功能退化。

Abstract

[Objective] The impacts of land use change on the ecosystem service value of various natural process were studied

in order to provide scientific basis for rational utilization of land resources and ecological security protection of the basin.[Methods] Based on the change of land use transformation

this paper analyzed the change of land use and the change of ecosystem service value in Yongjiang River basin under the influence of human activities from 1980 to 2015.[Results] ① The decrease of cultivated land and the increase of construction land were the main characteristics of land use change in Yongjiang River basin

whose degree of land use is rising. The land use types showed complicated mutual transformation

and the largest transfer area was from the conversion of cultivated land to construction land. ② During the past 35 years

the dynamic degree of land comprehensive utilization was 0.42%. The single dynamic degree of construction land use was the largest

and the reduction of cultivated land area was the greatest. ③ In terms of time

the total value of ecological services in the Yongjiang River basin increased first and then decreased

and increased continuously before 1995

but decreased continuously afterwards. ④ At the spatial level

the total value of ecological services showed a decreasing trend from southwest to northeast.[Conclusion] The transformation of land use in Yongjiang River basin was intense

and the rapid change of land use has aggravated the degradation of ecosystem function.
