| 摘要: |
| 从自然和投资方面评析了黄土高原农业生产与我国其他地区的差异，得出以下结论：（1）黄土高原脆弱的自然生态环境是其农业发展最主要的自然限制因素，其农业投资应立足于这一基本前提。（2）黄土高原 的农业投资滞后于农业发展的需求,农业无效投资 有增无减，农业投资份额下降，制约了农业产值的增长。对此，必须提高农业投资增长率，发挥国家投资的主体职能。（3）不合理的土地利用是导致生态环境严重破坏的更为直接的原因。对此,落实退耕还林种草，合理调整农业结构，建立与地面坡度相适应的土地利用结构并辅之以目标相符的投入，是进一步提高农业生产水平的关键。 |

| Analysis of natural environment and investment for agricultural production on Loess Plateau and its countermeasures |
|
|
| Abstract: |
| The agricultural production in Loess Plateau is analysed and evaluated from natural and investment aspects.The results show that the poor ecological environment of Loess Plateau is the most principal restrictive factor for its agricultural development,which is the prerequisite for agricultural investment.The investment for agriculture in Loess Plateau doesn't meet the needs of agricultural development;there is an increase in the invalid investment in agriculture,however,investment holdings in agriculture are decreasing,which restrained the agricultural output value's increase on Loess Plateau.So investment holdings in agriculture must be promoted to ensure the sustainable development in agricultural industry.Unrational use of land is the direct reason for the deterioration of ecological environment.So rational adjustment of agricultural structure,returning cultivated land for forestry and grass are the key of increasing agricultural production level. |
