1986～2010年河北坝上高寒区种植结构演化分析

Evolutionary Analysis on Planting Structure in Bashang Cold Area of Hebei Province from 1986 to 2010

运用定量分析与定性分析相结合的方法，对河北坝上高寒区1986～2010年种植结构演化进行了初步分析。结果表明：坝上高寒区粮食作物的主体地位没有改变，但粮食播种面积所占比例呈下降趋势；油料作物生产呈现震荡格局，极不稳定；蔬菜和水果生产发展迅速，其中“十一五”时期的蔬菜播种面积是“九五”时期的9.81倍。针对该区种植结构的基本特征和演化规律，提出了优化种植结构、合理配置农业资源的建议。

Using the methods of quantitative analysis and qualitative analysis , a preliminary study of the planting structure evolution in Bashang cold area of Hebei Province during 1986 -2010 was analyzed.The results showed that the dominant role of grain crops in Bashang extremely cold area was not changed , but the ratio of grain sown area had been declining.The production of oil crops was fluctuated, which was extremely unstable.The vegetable and fruit production were all grown fastly, among which the vegetable planting area in eleventh five-year plan period was 9.81 times than that of ninth five-year plan period.According to the basic characteristics and evolution law of planting structure in the area , the suggestion was put forward to optimize planting structure and allocate the agricultural resources reasonably.
