辽宁省农作物及自然物候对气候变暖的响应
Response of Liaoning Agricultural Crop and Phenology to Climate Warming
摘要
Abstract
Based on the climate data of recent 40 years since 1971 and phenology data of recent 25 years since 1982 in Liaoning Province, by using mathematical statistic, climate tendency rate, and geographic information system fine simulation, the significant changes of main agricultural crops and phenology in the wanning process were analyzed. TheResults were as follows: recent 40 years in Liaoning area, warming tendency is obvious, for annual average accumulated temperature above 10 ℃ from 2001 -2006 is 277.4 ℃ bigger than that of 1970s, and growing season get 13 days longer. Crop and phenology were sensitive to climate warming, so its planting belt got more north. During recent 36 years (1971 -2006) the suitable period of maize' seeding was 4 days ahead of time, and that of rice' growing was prolonged 8 days or so. Every 10 years during 25 years ( 1981 - 2006), the leaf - unfolding time of the herb was 2-4 days ahead of time in spring, and the scorch of herb and wood was postponed 5 - 7days in autumn.关键词
