摘要
撂荒地遥感提取方法主要为分类方法和变化检测方法。由于撂荒地覆被类型复杂,容易同草地、灌木混分,导致分类方法的提取精度不高。而变化检测方法易受非耕地变化因素干扰,且只能提取监测周期内的新增撂荒,无法提取监测周期之前的历史撂荒。此外,受遥感数据本身的制约,中低分数据受混合像元干扰而提取能力不足,高分遥感易受地形起伏、云层遮蔽、覆盖周期长等因素干扰而损失精度,因此,传统遥感方法提取撂荒地困难。本研究提出多源数据联合变化检测方法以提取撂荒地。利用多源数据的异质性和不同方法的互补性,针对不同类型的撂荒地制定不同的提取策略,并进行耦合分析以提取撂荒地。经实地调查验证,该方法提取总精度达到97. 6%。在此基础上,提取撂荒地的距离特征、高差特征、灌溉特征和邻域特征等自然地理指标,对其进行了显著性分析,判别了区域撂荒主导因素,为撂荒驱动力研究、定向提升撂荒地管理提供了依据。
