Analysis of Variation Characteristics of ClimaticP otential Productivity in Baoji City in Recent 55 Years
摘要
Abstract
In order to make clear the variation characteristics of climatic potential productivity in Baoji city , according to the measured values of daily air temperature and rainfall of Baoji city during 1960~2014 from Baoji Meteorological Station ( No. 57016) , we used Thornthwaite Memorial model to calculate the climatic potential productivity in Baoji city , and analyzed its vari-ation characteristics through comprehensively using climate tendency rate, accumulated anomaly method, Morlet wavelet function, Mann-Kendall non-parameter test combined with moving t-test, and Yamamoto analysis.The results showed that:in the past 55 years, the climatic potential productivity of Baoji city was 1105.7 kg/( hm2 · a) averagely, and it was decreasing at the rate of 0.87 kg/( hm2 · a) , and occurred a sudden change in the 1990s.The climatic potential productivity revealed multi-periodic changes, and its change periods were nearly 13, 22, 28 and 32 a.The rainfall was the dominant factor restricting the development of climatic potential productivity in this area;warming and humidifying were beneficial to the increase in the climatic potential pro-ductivity, and the warm and wet climate was best for the growth of agricultural crops .关键词
