摘要:
若尔盖高原沼泽湿地是我国面积最大的高寒沼泽湿地,在涵养水源、调节气候等方面具有十分重要的生态功能。本研究采用Arcgis版本,分别从1978年,1990年,2000年和2008年的中国湿地分布图中提取出若尔盖高原的湿地分布图,分析四个时期湿地的面积变化。发现若尔盖高原湿地面积由1978年的6170 km2下降至2008年的5379 km2,整体变化幅度为-12.83%,变化率为-0.43%。通过层次分析法对若尔盖高原湿地面积减少的驱动因子进行分析,发现导致湿地面积减少的主要因子是超载过牧、挖沟排水、降雨变化、鼠虫害、人口增长,其权重值分别为0.3801、0.1573、0.1386、0.0752、0.0733。上述结果表明若尔盖高原湿地在过去三十年呈退化趋势,而导致湿地退化的原因是自然因素和人类活动的共同作用。(图4 表4 参37)
Abstract:
Climate change and human activity have changed Zoige wetlands area significantly. However, how the area varied on Zoige wetlands in past 30 years remains poorly understood. This research quantified Zoige wetlands area variation tendency and rate from 1978 to 2008 with Arcgis and analyzed the driving factors with Analytic Hierarchy Process (AHP) methods. Result showed that Zoige wetlands area decreased 12.83% from 1978s (6170 km 2) to 2008s (5379 km2), with a decrease rate of 0.43%. We found that overgraze, drainage, precipitation change, rodent damage and population growth were the main driving factors of wetland area decrease, with driving weight of 0.3801、0.1573、0.1386、0.0752、0.0733, respectively. In conclusion, we found that Zoige wetlands have degraded continuously in past 30 years, with the co-function of natural factors and human activity.
