青藏高原沼泽湿地研究现状

青藏高原沼泽湿地是我国乃至世界最为典型的高原沼泽湿地之一。学术界一直都十分重视对它的研究。本文从湿地的演化(空间变化、时间演退等)和湿地的功能(生物多样性、湿地环境保护等)及湿地生产力等方面对青藏高原沼泽湿地的研究进行回顾,以期为后来的研究提供理论支持,提出今后的重点研究方向。

RESEARCH STATUS OF WETLANDS IN QINGHAI-TIBET PLATEAU

With pepper stems and leaves as raw material, added formic acid, corn flour, previously fermented juice, potato residue, after 45d bagged fermentation analyzing of its silage quality. The results show that ： pepper stems and leaves directly silage fermentation quality is poor; Each additive treatment improved silage fermentation quality, pH, AA, AN/TN, ADF and NDF were significantly lower than the control group （ P 〈 0.05 ）, BA produced less, LA, WSC and CP content was significantly higher （ P 〈 0.05 ）. pH of 1.5 % FA decreased largest; LA content of 5% PFJ is 2.94, is the lowest ; The WSC content of 100% corn flour treatments is the highest ; The DM content of 30% potato residue is 41.6, is the highest ; In all treatments, the fermentation quality of formic acid group on pepper stems and leaves silage is the best.
