选用铁卜加牧业气象试验站天然牧草历史观测资料,利用相关分析方法,探索天然牧草发育期、生长高度、覆盖度和产量等生长发育指标与前期不同时段降水量的相关显著性,模拟降水对天然牧草生长发育的长期效应。研究表明：无论是天然牧草的返青、开花、黄枯等发育期,还是5～7月牧草生长高度及月增加值和6～8月植被覆盖度,均与前期相关时段的降水量存在显著的相关性,从而对6～7月干草产量及其月增加量产生决定性的影响,充分说明降水对青海环湖天然牧草生长具有长期效应。

The effects of precipitation on natural grass in long term was simulated by using Tiebujia agricultural meteorological station natural grass historical record, using relative analysis method, explore natural grass growth period, growth height, covering, and production level, various growth factor, and apparent difference in precipitation of the different time period. The results showed that, regardless of natural grass regrowth, flower- ing, withering, various growth period, or May to July grass growth height and month increase and June to Au- gust plant covering, it was positive correlation between precipitation and previous time period, from June to July grass production level and monthly increaseing produces decisive effect, and it clearly indicated that lake pre- cipitation long term effected on natural grass growth.
