旱地种植业制约因素的分析及数学模型研究

Limiting Factor Analysis and its Mathematics Models in Dry Land Cropping,

旱地种植业发展的制约因素是影响农业发展、限制提高人民生活水平的重要原因。应用农业系统工程理论和曲线拟合方法建立数学模型,讨论种植业发展的制约因素,寻求旱地种植业的稳定、持续发展的途径,为有关部门提供策划、决策的参考依据。

Limiting factors in dry land cropping are important causes which affect agricultural development and hamper the rising of people's living standard. Mathematics models concerning the limiting factors were set up by agricultural system engineering theory and fitting of curve method, which explore possible approaches for a stable and sustainable development of dry land cropping, and provide references for decision-making organizations.
