摘要
基于2000-2008年土地利用的变化状况,对新疆伊犁河谷生态系统服务价值进行评价分析.结果表明:各类生态系统服务价值贡献率由大到小依次为:草地、水域、林地、耕地、未利用地;各县市单位面积生态系统服务价值由大到小依次为:特克斯县、昭苏县、尼勒克县、巩留县、霍城县、察布查尔县、新源县、伊宁县、伊宁市.2008年伊犁河谷生态系统服务价值总值达5 825 782.1万元,比2000年增加了6 076.9万元.土地利用效益与生态系统服务价值有着紧密联系.
Based on the land use change from 2000 to 2008, it was made an evaluation for the ESV of Ili Valley of Xinjiang. It evaluated the current situation of 2008 of the ESV of Ili Valley in detail, and showed that the contribution rate of the different styles of ESV by order was grassland, waters, woodland, and cultivated land, unused land; Among the different counties of Ili Valley, the unit area ESV from large to small as follows ： Tekes county, Zhaosu county, Nilka county, Tokkuztara county, Huocheng county, Qapqal county, Ktines county, Yining county, and Yining city. The results showed that the total ESV of Ill valley in 2008 amounts to 58. 257 821 billion Yuan, which was 60.769 million Yuan more than that of 2000. The evaluation showed that the ESV had close relationship with the land use ; the ESV appraisal may provide the reference for the regional sustainable land-use and the land utilization structure optimization. However, the evaluation theory of ESV and the calculation method should be further improved combined with the regional characteristics.
