对山东淄博市淄川水土保持生态修复区不同修复措施类型枯落物持水特征进行的调查和定位监测表明:①有林地封禁型植物群落枯落物蓄积量、饱和吸水率和饱和吸水量均较其他修复类型高;与修复前的荒草坡相比,天然林封禁和人工林封禁群落枯落物水容量分别增加25.85 mm和21.51 mm;疏林补植、荒坡造林、荒坡封禁和退耕还林型植物群落修复后枯落物蓄积量和水容量分别比修复前提高了22.74、54.96、22.11、28.70 t/km2和2.84、2.96、0.96、1.47 mm。②对现有森林植被实施封禁是生态修复的重要措施,在人工造林时,应尽量引进适生树种混交,以增加林地枯落物的蓄积量。
Investigation and location monitoring on the water holding characteristics of different types of restoration measures in Zichuan Soil and Water Conservation Area in Zibo, Shandong Province showed that: (1) the litter volume, saturated water absorption and saturated water absorption Which is 25.85 mm and 21.51 mm higher than that of the other restoration types. Compared with the pre-restoration weeds, the water capacity of natural forest blockages and litterfalls in the plantation community increased by 25.85 mm and 21.51 mm, respectively. The sparse forest replanting, slopes afforestation, barren slope closure and returning farmland to forests The litter volume and water capacity of the restored plant communities were increased by 22.74, 54.96, 22.11 and 28.70 t / km2, and 2.84, 2.96, 0.96 and 1.47 mm respectively than those before the restoration. (2) The embargo of existing forest vegetation is an important measure for ecological restoration. When artificial afforestation is adopted, mixed species of suitable tree species should be introduced as far as possible so as to increase the accumulation of forest litter.
