Crop residues are an important raw material for bioenergy. There is, however, obvious seasonality in crop harvests, and thus, a continuous supply of crop residues and its respective influencing factors should be investigated. In this paper, the impacts of geographical climatic conditions, characteristics of crops and the macroeconomic status exerted on the continuity of crop residue supply were analysed. Likewise, the effects of various factors on the supply of crop residues were examined. The results indicate that planting scale, crop diversity, climatic conditions, and topography have a significantly positive impact on a continuous crop residue supply, whereas the planting structure, temperature square term, energy pressure, and the economic development level have a significantly negative one. Finally, a regression-based decomposition method was used to measure the contribution rate of each variable onto the inequalities in the continuous supply of crop residues, which confirms that the impact of characteristics of crops on its continuous supply was the highest. The economic development level is the most important factor that affects the inequalities in the continuity of crop residue supply. The above results were achieved by using different measurement methods, and based upon the findings obtained, this paper proposes policies and suggestions for ensuring sustainable and bioenergy-oriented crop cultivation.

探索作物残渣持续供应的影响因素：从可持续和以生物能源为导向的作物种植角度

作物残渣是生物能源的重要原料。但是，农作物收成有明显的季节性，因此，应调查连续供应的农作物残渣及其影响因素。本文分析了地理气候条件，农作物特性和宏观经济状况对农作物残渣供应连续性的影响。同样，研究了各种因素对农作物残渣供应的影响。结果表明，种植规模，作物多样性，气候条件和地形对连续作物残渣供应有明显的积极影响，而种植结构，温度平方项，能量压力和经济发展水平则具有显着的负面影响。最后，使用基于回归的分解方法来测量每个变量对作物残渣连续供应中不平等的贡献率，这证实了作物特性对其连续供应的影响最大。经济发展水平是影响作物残渣供应连续性不平等的最重要因素。以上结果是通过使用不同的测量方法获得的，并且基于获得的发现，本文提出了确保可持续和以生物能源为导向的农作物种植的政策和建议。经济发展水平是影响作物残渣供应连续性不平等的最重要因素。以上结果是通过使用不同的测量方法获得的，并且基于获得的发现，本文提出了确保可持续和以生物能源为导向的农作物种植的政策和建议。经济发展水平是影响作物残渣供应连续性不平等的最重要因素。以上结果是通过使用不同的测量方法获得的，并且基于获得的发现，本文提出了确保可持续和以生物能源为导向的农作物种植的政策和建议。
