河西地区农业生产构成因素及其效益的分析

本文用通径系数法分析了农业生产的8个基本构成因素:种植业投入、养殖业投入、人口数量、劳动力数量、粮食作物面积、经济作物面积、人工草地面积、人均家畜数量及商品畜数量对6个农业效益如种植业产值、总收入、净收入、养殖业产值、总收入、净收入的重要性。发现不仅各构成因素间存在着相关关系,还直接或间接地影响各效益因素,认为在河西地区以种植业为主的农业生产系统中,发展经济作物、扩大人工草地、重视家庭畜牧业,走多种经营、农牧并举的道路,才能提高促进农业生产总效益。

The Agricultural Forming-factors and Their Benifits in Hexi Corridor

Hexi Corridor is a main commercial crop base. The current agricultural production in this area depends on the use of more and more fertilizers and insecticides, which made the soil fertility poor and the system weaken. In this paper, the eight agricultural forming-factors to their benifits were analyzed through the path-coefficients. The results showed that there were interrelations among the forming-factors, and the agricultural benifits were affected by these factors directly and indirectly, It is concluded that the cash crop and the artificial grassland area must be increased, and the livestock production must be emphasized. Thus lead a way to multiple management in existed agricultural system, which dominanted by plant, in order to gain the best benefits.
