摘要

汾河上游流域是黃土高原生態(tài)脆弱區(qū)獨立的流域單元,是山西省太原市惟一的供水之源,也是重要水源涵養(yǎng)區(qū),其土地利用方式直接影響著流域乃至山西省的生態(tài)安全。參照Costanza生態(tài)系統(tǒng)服務(wù)價值計算方法及生態(tài)經(jīng)濟協(xié)調(diào)度模式,定量分析汾河上游1990—2008年土地利用變化引起的生態(tài)系統(tǒng)服務(wù)價值和生態(tài)經(jīng)濟協(xié)調(diào)度的變化趨勢。結(jié)果表明,近20 a間,汾河上游流域生態(tài)系統(tǒng)服務(wù)價值呈現(xiàn)出先減少后增加的趨勢;其中林地面積的增加對生態(tài)系統(tǒng)服務(wù)價值貢獻較大,但水域面積的減少帶來生態(tài)服務(wù)功能價值減少,生態(tài)環(huán)境存在潛在危機;總體上,流域內(nèi)生態(tài)經(jīng)濟協(xié)調(diào)度有所改善,但仍處于低協(xié)調(diào)度的邊緣,尤其是流域范圍內(nèi)的寧武縣、嵐縣和靜樂縣。

Research on relationship between ecological environment and economic development is very important for a river watershed. The upper reaches of the Fenhe River watershed is an independent watershed unit in Loess Plateau and only an water supply area for Taiyuan, and land use change in the Fenhe River watershed is closely related to ecological safety in the watershed and the Shanxi Province. This paper analyzed the impact of land use change on ecosystem service values and ecology-economy harmony degrees in the upper reaches of the Fenhe River watershed during 1990-2008. Results showed that the ecosystem services values presented a trend of first decreasing and then increasing in the about 20 years; The increase of forest land brought increase of ecosystem services values, but the decrease of water area brought decrease of ecosystem services values, so the potential ecological crisis still existed in the watershed; The ecology-economy harmony degree improved during 1990-2008, but it was still in low level, especially in Ningwu, Lanxian and Jingle counties.
