摘要
Abstract
The characteristics of climatic variation and its impact on plant climate productivity were studied with the observed data of 14 meteorological stations from 1961 to 2014 in Chifeng . The results showed that annual average temperature increased significantly in 54 years, and the increase pace of warming was 0.87℃, the annual precipitation was slightly decreased. The regional distribution of plant climate productivity in south of Chifeng was better than in north, and the mean plant climate productivity in Chifeng was 6 992.88 kg/hm2·a.For two meteorological factors, annual precipitation was very significantly positive correlated with plant climate productivity, and annual average temperature was significantly negative correlated with, which implied the natural precipitation was important meteorological factor in determining plant climate productivity in Chifeng region.关键词
