- Abstract:
-
Energy change and sustainability dynamics of Harbin agricultural ecosystem from 2000 to 2009 were analyzed . The results showed that total energy use of agricultural ecosystem had the trend of constantly fluctuating. The agricultural ecosystem greatly depended on the un-renewable industrial auxiliary energy, moreover, the environmental load rate of Harbin was higher in China, and had big pressure on sustainable development. The direction of development on agricultural ecosystem in the future must focus on the development of water-saving irrigation agriculture; at the same time, the advanced technology must be introduced, and the input of intellectual resources should be increased. The government should adjust the investment of industrial auxiliary energy, and improve benefit response rate of energy; last but not least, explore and establish multi-level and high-function eco-agricultural model.
