摘要
根据陇东黄土高原6县区40年气候资料,分析光、温、水等主要气象要素的变化,结果表明:陇东黄土高原气候变化趋势与全国和全球相似,气温升高、降水趋少,向暖干化方向发展。通过气候变化对主要林果影响的分析,该区域适宜苹果、杏、枣的栽培,而桃、梨将由适宜栽培向次适宜栽培演化。因此,宜大力发展苹果、杏、枣栽培,调整桃、梨栽培面积。冬季气温增高可能导致果树病虫害加重,应引起高度重视。
Based on the climate datum from 1961 to 2000 in 6 counties which belong to Longdong loess plateau, the meteorological factors such as sunlight, temperature and precipitation have been analyzed. The result shows that the precipitation over the Loess Plateau decreased and temperature increased similar with the other areas in China and the whole globe and the Climate turns to warm-dry. It also shows that the region is suitable for planting apple, apricot and jujube etc. less suitable for pear, peach. Because of the comment above, the planting area of suitable and unsuitable fruit tree should be adjusted. The phenomenon of diseases and insect pests of fruit tree turns to be serious because of warming winter should also be paid much more attention to.
