Zusammenfassung:The invention discloses a slash recovery method. The slash recovery method comprises the steps that S1, water flow information of drainage ditches/water erosion gullies in a degraded slash is obtained; and S2, according to the water flow information, comparing each index in the drainage ditch/water erosion gully with each preset condition in one-to-one correspondence with each index to obtain a plurality of comparison results, and according to each comparison result, generating a restoration scheme of the degraded slash. The method can effectively slow down the flow velocity of a water body to raise a ditch bed, guarantees hydrological communication, has the characteristic of low maintenance, and can promote siltation, improve the vegetation coverage rate and promote the health of a wetland ecosystem. 本发明公开了一种迹地恢复方法,所述迹地恢复方法包括:S1:获取退化迹地中排水沟渠/水蚀沟壑水流信息;S2:根据所述水流信息,对比所述排水沟渠/水蚀沟壑中的各项指标及与各项指标一一对应的各预设条件,得到多项对比结果,并根据各项对比结果,生成退化迹地的恢复方案。本发明能够有效减缓水体流速抬高沟床,保障了水文连通,并具有低维护的特点,且能够促进淤积,提高植被覆盖率,促进湿地生态系统健康。
