摘要

土壤保持服务是生态系统服务中调节服务的一项重要内容

无定河流域水土流失严重

土壤保持服务成为其首要的生态系统服务。利用SWAT模型和GIS对无定河流域土壤保持服务供需平衡和空间流动路径进行探究分析

揭示无定河流域土壤保持服务供需空间匹配特征及其空间流转机制。结果表明:(1)无定河流域土壤保持服务供给量与需求量变化趋势具有较强的一致性

两者都呈波动上升的趋势

均与降水具有较强的相互对应关系。其中

2001年8月、2013年7月、2017年7月供给量及需求量达到了2000—2020年所有月份中的较大值

供给量均超过2.5×108 t

需求量则均超过了3.5×108 t。相应地

月均降水量在这3个月也达到了较大值。(2)2000—2020年无定河流域亏损月份多于盈余月份

且亏损量呈增加趋势。中上游地区为盈余状态

供略大于需

中下游地区表现为亏损

且需远大于供;(3)对减沙服务空间流动路径模拟

在此基础上获取了各子流域减沙服务流量及受益量。2000—2020年流域内减沙服务流量波动性增多

尤其2020年在下游地区增长明显;减沙服务受益量在流域内具有累加效益

研究期间总体呈上升趋势。研究结果为流域水土流失治理提供新的视角

对生态修复和水土流失防治政策制定具有重要参考价值。

Abstract

Soil and water loss is serious in the Wuding River Basin

so soil conservation service becomes the primary ecosystem service. Based on SWAT model and GIS

the balance between supply and demand of soil conservation service and spatial flow path were analyzed to reveal the spatial matching characteristics and spatial flow mechanism of soil conservation service in the Wuding River Basin. The results showed that there was a strong consistency between the supply and the demand of soil conservation service in the Wuding River Basin

and both of them showed a trend of fluctuant increase and had a strong correlation with precipitation. The supply and demand in August 2001

July 2013 and July 2017 reached the larger value in all the months from 2000 to 2020

with the supply exceeding 2.5×108 t and demand exceeding 3.5×108 t. Correspondingly

the monthly average precipitation also reached a large value in these three months. From 2000 to 2020

the deficit months were more than the surplus months

and the deficit was increasing. The middle and upper reaches were in surplus

with the supply slightly greater than the demand

while the middle and lower reaches were in deficit

with the demand far greater than the supply. The spatial flow path of sediment reduction service was simulated. On this basis

the flow and benefit of sediment reduction service in each subbasin were obtained. The fluctuation of sediment reduction service flow increased from 2000 to 2020

especially in the downstream area in 2020. The benefit of sediment reduction service had accumulative benefit in the basin and showed an increasing trend during the study period. The results could provide a new perspective for the control of soil erosion in watershed

and have important reference value for ecological restoration and policy making of soil and water loss control.
