摘要
稳定的生境质量是维持生态系统生物多样性的重要基础,迄今为止,我国设立了多个生物多样性生态功能区,但有关其生态质量状况的研究较少,针对这一现象,选取秦巴生物多样性生态功能区作为研究区,采用In VEST模型和Mann-Kendall趋势检验方法,获取了研究区生境质量指数和生态系统生产力变化趋势,以此监测研究区生境质量在2000-2010年间的时空变化情况。结果表明,2000-2010年间,研究区生境质量虽然略有小幅变化,但整体上基本保持稳定,无明显变化。
The stable ecological quality plays an important role in sustaining the biodiversity,China has established several eco- functional areas of biological diversity,however,the study on the ecological quality is less. Therefore,we took Qinba eco- functional area of biological diversity as the study area,used In VEST model and Mann- Kendall trend test method,obtain the habitat quality index and changing trend of ecosystem productivity to monitor the temporal and spatial variation of the habitat quality from 2000 to 2010. The result showed that the habitat quality remained stable overall in the study area,despite some fluctuation.
