The culture and landscape of Shaanxi Province are representative of Northwest China. Despite the current prosperity of tourism, the issue of sustainable development of cultural industry in Shaanxi Province is emerging increasingly. We analyzed the challenges and prospects for cultural industry in Shaanxi Province using the SWOT (Strength, Weakness, Opportunity and Threat) approach, in combination with the analytic hierarchy process (AHP). We used preferential data from local experts who have an extensive and diverse understanding of cultural industry of Shaanxi Province. The results reveal that strengths and opportunities for cultural industry in Shaanxi Province outweigh its weaknesses and threats. The experts believed that the abundant resources in landscape and history are the major strength, and the huge demand in the Chinese market is the important opportunity. While the lag in social concept and governmental execution is identified as a weakness for the development of cultural industry, Western cultural impact and domestic/intra-regional competitions are considered to be the critical threats. The quantitative analysis of the strategies indicates the strength/opportunity strategy is the optimal one for the sustainable development of Shaanxi's cultural industry.

Since our country put forward the rural revitalization strategy, we have attached great importance to the construction and development of urban and rural areas. In recent years, we have continuously enhanced the driving force of development and further promoted rural reform. However, in the construction of rural cultural industry, how to purify environmental pollution is a key and difficult point. Through the comprehensive analysis of the role and effect of biomaterials in environmental pollution purification, this study compares the comprehensive role of different materials in environmental purification, compares the trend of environmental pollution in the development of rural industries in recent years, and analyzes the coupling degree of environmental pollution purification in different technological environments. Through the analysis, we can draw a conclusion that under the action of nanomaterials and biomaterials, some water pollution, air pollution, construction waste pollution, and noise pollution in industrial development have achieved good results and impact. Through continuous practice and research, it can be seen that biotechnology and materials can play a relatively good role in the environmental pollution control. And this treatment technology has the advantages of low cost, high efficiency, and no secondary pollution. It also plays an important role in the treatment of pollutants and the development of new energy. It conforms to the concept of sustainable development and environmental construction in the modern society and provides more reference data and research value for the future research and development prospects of nanomaterials and biomaterials in industrial development and environmental governance.
