中文摘要:
      [目的] 对西安市泾渭湿地自然保护区生境质量变化进行研究,为保护区未来环境保护和发展提供科学参考。[方法] 基于InVEST生物多样性模型,结合土地利用/土地覆被变化,从保护区整体、分区到土地利用/土地覆类型分别对保护区生境质量进行分析。[结果] ①2006—2016年,保护区内农田急剧减少,对草地、森林和湿地面积的增加贡献较大。②保护区生境质量呈上升趋势,局部有所下降,整体生境质量中等。③保护区所在各区生境质量由高到低依次为灞桥区、未央区、高陵区,生境质量指数平均值分别较2006年增长了21.05%,50.01%,37.84%。[结论] 人工生境包括交通用地、居住地、工业用地和耕地对生态环境的干扰是生境质量下降的主要驱动因素。天然生境包括湿地和森林对保护区生物多样性维持功能贡献较大,保护区森林面积略显不足。
英文摘要:
      [Objective] The change of habitat quality of Jingwei wetland nature reserve in Xi'an City was investigated to provide scientific reference for the future development and environmental protection of the reserve.[Methods] Based on the InVEST biodiversity model and land use/cover data, this study analyzed the habitat quality of the reserve.[Results] ① In 2006-2016,the farmland was severely decreased and mainly converted to the grassland, forestland, and wetland. ② The habitat quality of the reserve showed an increasing trend, and a decreasing trend in some areas, Meanwhile, the whole habitat tended to be medium. ③ Among the three districts, the habitat quality of the Baqiao is the highest, followed by the Weiyang and then the Gaoling. Compared with 2006, their habitat quality in the 2016 increased by 21.05%, 50.01%, and 37.84%, respectively;[Conclusion] The main driving factor of habitat degradation is the artificial habitat including traffic land, residential land, industrial land, and farmland. Natural habitat including wetland and forest is beneficial to the maintenance of biodiversity, but the forest area is slightly insufficient in the reserve.
