Study of response of northern pediment plain of Qinling Mountains to global warming and its impacts on fruit development
秦岭北麓平原对全球变暖的响应及其对果业发展的影响研究

All countries in the world are paying more and more attention to global change.Glo-bal change has regional diversities.In order to find out it's regional characteristics,statistical,regressive and trend analysis are used in this paper.Based on climate data on the northern pediment plain of Qinling Mountains from1959to1999,the study indicated that climate in the region become warmer and dryer during the last41years.Sunshine hours have been decreasing due to air pollution.Climate evaluation for apple plantation indicates that climate becomes unsuitable for apple growth in this area.High temperature in summer,higher relative humidity and the shorter sunshine hours will affect apple growth,resulting in further decline of apple quality and the aggravation of apple diseases and insect pests.Therefore the other types of fruits such as grapes,peaches and persimmons can be developed and the acreage of apple can be reduced.
