天水市气候资源特点及种植业结构调整研究——以麦积区为例

A study on Characteristic of climatic resources and adjustment of planting structure——Take Maiji district of Tianshui as an example

从天水市麦积区土地资源现有利用状况出发,系统分析该地气候资源对农业生产影响的利弊程度及现有农业种植结构对气候资源的有效利用程度,并依照有利于农村经济可持续发展、生态环境良性循环等原则,运用线性规划模型对该地的农业种植结构进行了分析规划。实施规划,当地的夏、秋粮及经济作物的种植比例会更趋合理,种植作物总产值有望比原来增加了14.4%。

According to the land resource of Maiji district of Tianshui, the influence of climatic resource on the agricultural production and the available utilization degree of agricultural planting structure has been analyzed. According to the principle of the sustainable development of the rural economy, ecological environment benignity movement and so on, the agricultural planting structure has been analyzed and planed using the linear programming model. The result shows that the planting proportion of local summer crops, autumn crop and commercial crop is more reasonable than before, the total value of planting output increases by 14.8%, the plan ning goal has achieved. The scientific theoretical foundation for the availability of climatic resources and agricultural development has also been provided.
