The current industrial structure of eco-fragile areas fails to reverse the trend of the deterioration of the ecological environment and severely affects the sustainable development of eco-fragile areas, so conducting scientific and technological studies of ecological industries and ecological products helps eco-fragile areas recover their degraded ecosystem. The results of a statistical analysis of 159 related documents show: (1) the number of documents published rises wave upon wave in time series, which indicates that this area of study is still at the stage of rising; (2) research contents concentrate on five dimensions-theoretical research, technology research and development, model building, demonstration and promotion, and efficiency analysis, among which theoretical research chiefly discusses environmental costs and effects of ecological industries, regional organizational layout, industrial chain construction, market supply and demand of biological products, discrimination of the nature of biological products, and value assessment and realization of biological products; (3) study areas are largely distributed in the Loess Plateau area in the north and karst areas in the south in China, which suggests that studies of biological industries and biological products in eco-fragile areas concentrate on arid and semi-arid areas and engineered arid areas. Furthermore, from five aspects-theoretical study, technology research and development, model building, experiment and demonstration, and monitoring and evaluation, this study reveals cutting-edge theories about ecological industries and ecological products in eco-fragile areas. At last, it is found that comprehensive theoretical research of the market circulation of ecological products in eco-fragile areas and the research and development of key technologies to enhance the value of ecological products lag behind, and it is necessary to deepen the studies about the whole industry chain development for ecological industries, the valuation of ecological effect, the standardization of ecological industry management, the circulation mechanism of ecological products, brand building and other aspects.
当前生态脆弱区的产业结构未能扭转生态环境恶化的趋势，严重影响了生态脆弱区的可持续发展，因此开展生态产业和生态产品的科技研究有助于生态脆弱区恢复退化的生态系统。对 159 篇相关文献的统计分析结果表明：（1）文献发表数量在时间序列上呈波浪式上升，表明该研究领域仍处于上升阶段；（2）研究内容集中在理论研究、技术研发、模型构建、示范推广和效率分析五个维度，其中理论研究主要探讨生态产业的环境成本和效益、区域组织布局、产业链建设、生物产品的市场供求、生物产品的性质判别、生物产品的价值评估和实现等；（3）研究区域主要分布在中国北方的黄土高原地区和南方的喀斯特地区，这表明生态脆弱区生物产业和生物产品的研究主要集中在干旱半干旱地区和工程干旱地区。此外，从理论研究、技术研发、模型构建、实验示范和监测评估五个方面，揭示了生态脆弱区生态产业和生态产品的前沿理论。最后，发现生态脆弱区生态产品市场流通的综合理论研究和生态产品增值的关键技术研发相对滞后，有必要深化生态产业全产业链发展、生态效应评估、生态产业管理标准化、生态产品流通机制、品牌建设等方面的研究。
