摘要
植物篱技术作为水土保持与农业面源污染的源头控制措施,已被广泛地研究应用于世界各国.在介绍植物篱技术概念、分类的基础上,综述了植物篱技术的效益及其评价的国内外研究现状,植物篱的生态效益集中体现在保持水土,改善微地貌,提高土地生产力与控制农业面源污染上.植物篱的效益评价存在评价内容与指标片面,评价结果可比性差等不足之处,最后,就植物篱技术效益及评价研究的相关问题提出展望.
Abstract
Hedgerow technique has been used as a soil and water conservation measure and source control technique of agricultural nonpoint source pollution and it has been widely applied in the world. Based on introducing the definition and types of hedgerow technique, the domestic and international research status of the hedgerow technique's ecological benefits, economic benefits, social benefits, landscape benefits and benefit evaluation were summarized. Among them, the hedgerow's ecological benefit is reflected mainly in conserving soil and water, improving microiopography, increasing land productivity and controlling agricultural non-point source pollution. The problems were disclosed in the current benefit evaluation of the hedgerow, such as incomplete evaluation content and indices, poor comparability of evaluation result Finally, the research prospects of the related problems in the hedgerow's benefits and benefit evaluation were put forward.
