摘要: 疏勒河流域属于典型的干旱区内陆河流域,生态环境脆弱,对其进行生态系统质量评价意义重大.本文利用多源遥感数据,依据生态系统生产能力指数(EPI)/生态系统稳定性指数(ESI)/生态系统承载力指数(EBCI),建立遥感综合评价模型,对疏勒河流域2001—2010年的生态系统质量进行综合评价.结果表明: 疏勒河流域2001—2010年生态系统质量平均值为43.21,处于较低水平.EPI、ESI和EBCI的均值分别为47.16、58.09和28.52,说明疏勒河流域生态系统承载力较低.2001—2010年,EPI和EBCI分别增加了18.9%和20.1%,ESI下降了9.4%.流域生态系统质量总体呈现出先增加后下降的趋势,2001、2005和2010年生态系统质量年均值分别为 43.71、44.80和41.13.农田生态系统质量最高,水体生态系统质量最低.人工生态系统质量综合评价值为46.43,明显高于自然生态系统.

Abstract: Shule River Basin is a typical arid inland river basin and ecoenvironment-fragile region. Comprehensive evaluation of ecosystem quality in the Shule River basin is of great significance. The ecosystem productivity index (EPI), the ecosystem stability index (ESI) and the ecosystem bea-ring capacity index (EBCI) were proposed to build a remote sensing comprehensive evaluation mo-del to evaluate the ecosystem quality of Shule River basin during 2001-2010. The results showed that the mean ecosystem quality value in the Shule River basin was 43.21, which was at a relatively low level. The values of EPI, ESI, EBCI were 47.16, 58.09 and 28.52, respectively, indicating that ecosystem carrying capacity in the Shule River basin was poor in the period from 2001 to 2010. However, EPI and EBCI rose by 18.9% and 20.1%, respectively, but ESI decreased slightly by 9.4%. The ecosystem quality showed a trend of increasing first and then decreasing from 2001 to 2010. The average ecosystem quality values in 2001, 2005 and 2010 were 43.71, 44.80 and 41.13, respectively. The farmland ecosystem quality was better than that of the other ecosystem types, and the water area ecosystem quality was the lowest. Overall, the comprehensive evaluation value of the artificial ecosystem quality was 46.43, which was significantly higher than that of the natural ecosystems.
