不同气候年型对荒漠植物生长的影响
Growth of Desert Plants in Different Climate Years
摘要
Abstract
In this paper,the phenology change and growth of Haloxylon ammodendron and Cornulaca alaschanica at Agrometeorological Station of Wuwei Meteorological Bureau, Gansu Province were analyzed based on the stationed observation data.The results are as follows:① The phenological period of H.ammodendron in spring of warm-dry years was 2 to 7 days earlier than that in normal years, but that in autumn was 2 to 11 days later.The phenological period of C.alaschanica in warm-dry years was 21 to 120 days later than that in normal years.The phenological period of C.alaschanica in spring and summer of cold-wet years was 3 to 13 days earlier than that in normal years,but that in autumn was 11 days later;② The shoot length of H.ammodendron in spring and autumn of warm-dry years was longer than that of cold-wet years, but that in summer of warm-dry years was shorter than that of cold-wet years.The height of C.alaschanica in warm-dry years was lower than that in normal years, but it was higher in cold-wet years than that in normal years:③ The biomass of H.ammodendron was higher in early period of cold-wet years but lower in late period, and it was higher in warm-dry years than that in cold-wet years.The biomass of C.alaschanica per unit area in cold-wet years was much higher than that in warm-dry years;④ The coverage of H.ammodendron in cold-wet years was high, but that of C.alaschanica was increased with the increase of precipitation;⑤ Temperature and precipitation were the main factors affecting the growth of H.ammodendron and C.alaschanica's main influence factors.关键词
