摘要:
生态系统变化会引起景观结构及格局的改变,而景观格局及其演化可以作为评价环境变化的指标。为了揭示浑善达克沙地生态系统变化特征,该文使用陆地卫星(Landsat 5、7)的TM/ETM+资料及地面调查数据来分析沙地景观变化特征。通过计算机监督分类,获得了研究区1987和2000年景观类型数据,研究区的景观类型有草地、固定沙地、半固定沙地、流动沙地、灌木林及水体。通过对两期景观数据的基本特征、变化检测及转移矩阵分析发现:1)从1987到2000年,草原、固定沙地、半固定沙地都在减少,斑块破碎,而流动沙地显著增加,成为主要景观类型,同时斑块相互联合形成两条流动沙带;2)类型转移上,草原转为沙地,固定沙地主要转为半固定沙地,半固定沙地以绝对优势转为流动沙地,水体转为流动沙地及草原;3)变化监测显示,流动沙地增加面积远远大于减少的面积,而草原、固定沙地、半固定沙地呈现相反趋势,变化区域的空间分布也不尽相同。结果表明研究区沙地生态系统已经退化比较严重,特别是流动沙带的出现,需要采取积极有效的防治措施,防止进一步扩大。
