摘要:
以天山大小莫合流域野果林区为例,探究其景观格局的时空演变特征及揭示滑坡对野果林区造成的生态风险具有重要意义。以Corona和Spot-5等高分辨率遥感影像为数据源,通过RS技术解译1964、1980、2000、2017年空间数据,利用 Fragstats 4.0软件计算景观特征指数,并探讨了滑坡景观格局时空变化特征与演化的驱动因素,从而进行景观生态风险预测。结果表明:(1)1964—2017年野果林面积持续减少了3942.15 hm2,主要向草地、耕地转移面积为主,滑坡区面积增加了203.48 hm2,其主要转入景观类型为野果林、草地。(2)野果林区各景观破碎程度加剧,景观边界形状总体上趋于复杂。不同景观斑块面积呈现不均匀状态,景观的空间异质性增强。(3)滑坡景观类型变化受自然因素和人文因素共同影响作用。人口增加和人为干扰度是主要的人文驱动因子,气温、坡度、坡向和降水是主要的自然驱动因子。(4)2017年景观生态风险以高风险等级和较高生态风险等级为主,此阶段,野果林区生态系统稳定性低,其生态环境脆弱; 2034年滑坡景观生态风险有减弱趋势,野果林区生态系统趋于稳定,但滑坡等自然灾害仍不容忽视。
