随着生态湿地技术在我国的规模化推广应用,湿地植物资源的管理和利用途径成为新的挑战.将湿地植物刈割并移至陆地生态系统是水体系统污染控制的终极途径之一.概述了在资源紧缺和环境污染双重背景下,湿地植物资源管理和利用的潜在途径.以南方某133.3 hm2规模化湿地为例进行估算,通过植物刈割,可以直接带走450 kg/a磷、9 540 kg/a氮,从而避免潜在二次污染.总结了植物刈割的方法、参数及对湿地的影响.综述了刈割转移生物质的几种潜在后续利用方式:燃料、纤维、工业材料、饲料、肥料及生物炭等.指出在我国目前社会经济背景下,湿地生物质资源二次利用具有广阔的前景和深远的环保意义.

With the increasing application of ecological wetlands in China, the approaches to managing and utilizing massive wetlands macrophytes are becoming an urgent new practical challenge. Transferring the harvested wetland plants from aquatic ecosystems to terrestrial ecosystems is one of the ultimate pathways of aquatic pollutants removal. This mini-review, as such, summarized the potential approaches of wetlands plants resources management and regenerative utilization, under the coupling circumstances of natural resource shortage and environmental pollution. As estimated in a 1.33 km2 wetland in South China, the plant harvesting can remove 450 kg phosphorus (P) and 9 540 kg nitrogen (N) per year directly from wetland system, thus avoiding the potential secondary pollution. The reaping methods, reaping season and frequency, and the effects of plant harvesting on the wetlands were compared and brielfy reviewed. Several potential models of subsequent utilization of the harvested plant biomass such as being made into fuel, fiber, industrial production, fertilizer, fodder, and biochar were reviewed. The promising future and far-reaching environmental signiifcance was emphasized on the secondary utilization of wetland bio-resources under the current socio-economic background.
