摘要
本文选取二连油田蒙古林作业区生态环境质量为研究对象,对该区域内的土地利用/覆盖状况、植被状况、景观类型及其破碎度进行定性、定量研究。结果表明:(1)2008年,该区域土地利用类型主要为有林地、中覆盖度草地、低覆盖度草地、工矿交通建设用地和盐碱地等;工交建设占地明显。(2)该区2008年主要植物群落类型有:克氏针茅+羊草+杂类草、克氏针茅+锦鸡儿+杂类草、羊草+针茅+杂类草等;受到气候变暖等原因影响,小针茅已经在本区广泛分布。(3)该区2008年主要景观类型为针茅+锦鸡儿草原景观、针茅草原景观、羊草草原景观、林地景观、人工建设区景观和道路景观;景观破碎度较高,人为干扰较为严重。建议相关单位足够重视并采取切实可行的措施,防止本区生态环境恶化。
