摘要:
为了掌握大通北川河源区国家级自然保护区生态系统与生境质量变化状况,优化保护对策与措施,基于2005年、2010年、2015年3个时间节点,分析了保护区土地利用和植被覆盖度的变化。在此基础上,基于InVEST模型中生境评估模块进行保护区的生境质量评估,并运用植被覆盖度(VFC)来修正生境适宜度(H)指标,进而得出了更加精确的生境质量评估结果。结果表明:保护区土地利用主要以灌木林、草地、裸地为主。2005—2015年土地利用变化不大,主要有小部分地区裸地转换为草地,保护区整体生境质量显著提升,尤其是北部与南部地区的灌木林,这与保护区植被覆盖度的分布规律基本吻合。因此,通过相关措施,减少人为干扰,增加林草植被盖度,是提高保护区生境质量的有效措施。
Abstract:
In order to grasp the change trend of ecosystem and habitat quality in Datong Beichuan Heyuan River Source Area National Nature Reserve and optimize the protection countermeasures and measures, the changes of land use and vegetation coverage in the National Nature Reserve of Datong Beichuan River source area were analyzed based on the three time nodes of 2005, 2010 and 2015. Based on the habitat assessment module of invest model, the habitat quality of the reserve was assessed, and the vegetation coverage(VFC)was used to modify the habitat suitability(H)index, so as to get more accurate results of habitat quality assessment. The results showed that shrubbery, grassland and bare land were the main land uses in the reserve area; from 2005 to 2015, the change of land use was not significant, a small part of bare land was converted to grassland, the overall habitat quality of the reserve area was significantly improved, especially the shrubbery in the north and south, which was basically consistent with the distribution pattern of vegetation coverage in the reserve area.
