Analysis of natural environment and investment for agricultural production on Loess Plateau and its countermeasures

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.
