The Response Of Agricultural Production In Shuangfeng Forest Area To Climate Change

The Shuangfeng forest area is affected by both the maritime environment and the continental monsoon.In addition to the high altitude here,due to the influence of the small climate of the mountain,the Shuangfeng forest area has abundant rainfall in summer,early snowfall in winter and long snow period.It is the largest snowfall area in China..In recent years,due to excessive forest harvesting and a sharp decline in forestry resources,the state has implemented natural forest protection projects throughout the forest area.The local government has vigorously developed agriculture in recent years,especially in the crop industry.In the planting industry,self-cropping crops such as soybeans and rice are large in area and have a wide range of cultivation.Due to the fertile soil and abundant water resources,Shuangfeng Forest has suitable climatic conditions and superior geographical advantages in agricultural production.However,in recent years,due to global climate change,such as rising global temperatures and increased natural disasters,agricultural production in the area faces enormous challenges.The impact of climate change on agricultural production is not only related to food production and safe supply,but may also affect the quality of agricultural products and food safety.Agricultural production is increasingly affected by climate change,so it is imperative to study the response of climate change to agricultural production.This study is based on the main crops(rice,corn,soybean,potato,cabbage)in Shuangfeng forest area.Based on meteorological data(temperature and precipitation)and crop data,systematic analysis of rice and corn for nearly 30 years and soybeans,potatoes,The temporal and spatial evolution pattern of climatic resources in 20 years of Chinese cabbage,the following conclusions were drawn:1.From 1987 to 2017,the annual average temperature in Shuangfeng area was2.75 °C.Before 2000,the average annual temperature was 2.50 °C.During 2000-2017,the average annual temperature was 2.98 °C,and in 17 years it increased by 0.48 °C.2.From 1987 to 2017,the annual average precipitation was 610.38 mm.Between 1987 and 2000,the annual average precipitation was 638.21 mm.During2000-2017,the annual average precipitation was 586.03 mm.During the 17 years,the annual precipitation decreased by about 50 mm.3.According to the temperature correlation analysis,the yield per mu of rice,corn,soybean and economic crops was positively correlated with temperature,and the yield of rice,soybean and corn was reached at the level of 0.05.Significant.4.There is a negative correlation between precipitation and the yield of main crops in Shuangfeng area.At the significance of 0.05,the correlation coefficients of rice,corn and soybean are-0.290,-0.124,-0.171,respectively.The annual precipitation is not significantly correlated.The correlation coefficients of potato and Chinese cabbage were-0.565 and-0.672,respectively,and both reached significant levels.5.In the short term,according to the current trend of temperature and precipitation in Shuangfeng area,it has a favorable impact on agricultural production in Shuangfeng area.
