“…The so-called low-carbon economy refers to under the guidance of the concept of sustainable development, through the technological innovation, system innovation, the industrial transformation, new energy development and other kinds of means, achieving a win-win economic development form with economic and social development and ecological environment protection, by way of reducing the high carbon energy consumption such as coal and oil, and reducing greenhouse gas emissions. For the understanding of new countryside's low-carbon economy, it means to achieve a rural win-win economic development form with rural sustainable economic development and ecological environment protection when constructing the new rural of socialism, by way of accelerating the farmers' low-carbon living, the low-carbon development of agriculture, forestry, animal husbandry and fishery as well as reducing the greenhouse gas emissions under the guidance of the concept of sustainable development [2].…”

This paper first defines the elements and meaning of rural low-carbon economy. On the basis of theoretical analysis, this paper then analyses the government role in the development of rural low-carbon economy, for example, government should organize and coordinate the development of rural low-carbon economy, should increase the investment of rural low-carbon economy, and should supervise rural low-carbon economy development as well. Last, the paper gives some suggestions for government to follow in the future work.

Forest–agriculture complex management is an efficient planting mode that can effectively improve soil utilization and bring greater economic value. However, this planting model has not yet been systematically carried out in the northeast of China. Thus, to provide a theoretical basis for agriculture and forestry intercropping in northeast China, the variation in the growth and wood characteristics of Populus cathayana × canadansis ‘xin lin 1’ and the economic benefits of intercropping crops under different intercropping patterns were analyzed. The results of a variance analysis show that there were significant differences in tree growth and wood characteristics among the different intercropping modes (p < 0.01). The variation coefficients of growth and wood characteristics ranged from 28.23% to 55.79% and 2.03% to 10.65%, respectively. There were significant correlations among tree height, diameter at breast height, ground diameter and wood volume of ‘P. ‘xin lin 1’, as well as between cellulose, hemicellulose, lignin, fiber length and fiber aspect ratio (r < 0.05). Meanwhile, we comprehensively evaluated intercropping modes based on growth traits such as tree height, chest diameter, diameter, wood volume and crown width. The ‘P. ‘xin lin 1’ + soybean’ mode proved to be the best intercropping mode, in which the gain of tree height, chest diameter, diameter, wood volume and crown width were 26.80%, 20.09%, 15.76%, 63.41% and 8.33%, respectively. When considering wood traits, the optimal intercropping pattern was ‘P. ‘xin lin 1’ + Cilantro + Cabbage’, but the gain of each wood trait in this pattern was not obvious compared with the total average. Among the six intercropping modes, ‘P. ‘xin lin 1’ + Watermelon + Chinese cabbage’ and ‘P. ‘xin lin 1’ + Cilantro + Chinese cabbage’ have the highest economic benefits, reaching 48,138 CNY/hm2 and 39,990 CNY/hm2, respectively. From our results, the poplar growth and wood characteristics under different intercropping modes are better than those of the pure forest, except for ‘P. ‘xin lin 1’ + Corn’, and each intercropping mode has higher economic benefits. These findings provide a scientific basis for alleviating the competition between local forestry and agriculture for land and address the selection of forestry and agricultural intercropping modes.
