中国沙产业已发展20多年，产业内容日趋丰富，为中国沙区生态环境改善、地方经济发展及农牧民收入提升方面做出了贡献。沙产业积极向好发展的同时广大学者提出新的问题：当前沙区沙产业融合发展模式有哪些？融合机理是什么？融合程度如何？融合过程中存在哪些问题？这些问题不解决，将不利于沙区沙产业的进一步发展。因此，在分析当前沙产业发展与融合现状的基础上，总结归纳出沙产业融合发展的3种模式（产业交叉型、产业链延伸型及技术渗透型），并分析其融合机理。最后结合典型企业具体分析其融合程度并指出沙产业融合发展过程中存在的主要问题（目前沙产业的融合程度所处水平较低，融合稳定性不强等），进而提出围绕“沙产业+”，推行沙产业交叉型融合发展，延伸沙产业融合链条，激发沙产业各部分活力等相关政策建议。

Deserticulture has a history of more than 20 years, which is becoming more and more abundant and has contributed to the improvement of ecological environment, the revitalization of local economic and alleviation of poverty in China's desert areas. It also raises new questions for scholars: what kind of convergence mode for deserticulture currently? How about the convergence mechanism and extent? If these problems are not well solved, it will not be beneficial to the further development of the deserticulture in the desert area. Therefore, based on the analysis of the current situation of development and convergence of the deserticulture, three modes of the convergence for the deserticulture were summarized: industrial cross-type, industrial chain extension and technology penetration. Then, convergence extent was analyzed based on three cases. The results show that there are some problems in the process of deserticulture convergence. The convergence extent is low and the stability of the convergence is not high. Finally, some policy suggestions on the development of deserticulture in China were proposed to focus on the “deserticulture +”, promote the cross-type convergence mode of the deserticulture, extend the convergence chain of deserticulture, and stimulate the vitality of various parts of the deserticulture.
