It also preliminarily analyses the existing problems of rural ecotourism. Then countermeasures and suggestions related to the further development of rural ecotourism and promotion of new countryside construction are put forward, which can be summarized as follows: carrying out multichannel financing, in order to strengthen the development dynamics of rural ecotourism; focusing on cultivation of ecological quality consciousness, in order to enhance the protection of resources and the environment; innovating development ideas, in order to create muti-function areas; intensifying the efforts on the training for employee, in order to upgrade comprehensive service level; promoting community participation and intensifying the efforts on the training for farmer, in order to raise farmer's consciousness about development of ecotourism; strengthening the fusion of ecology and culture.展开更多

There are many problems in the process of new socialist countryside construction,including no supply and management system for rural public service products,no agricultural ecological compensation mechanism,increasingly prominent rural hollowing and decline of passing on economic culture,lack of funds and technologies for new socialist countryside construction,and inadequate understanding of new socialist countryside construction. In line with these problems,it came up with recommendations and countermeasures for beautiful countryside construction in Jiangsu Province in the new period from government guidance,plan leading,industrial support,environmental improvement,innovation management and cultural cultivation.展开更多

Tetraethoxysilane was used as the silica source. The specific surface area and total pore volume of the product reached 772.3 m2/g and 0.663 cm3/g, respectively. The electrolyte washing process conferred a surface charge to the product, which displayed self-dispersal properties in water. The porous spheres have potential applications in the fields of drug delivery, controlled release capsules, indoor air pollutant scavengers, and hydrogen storage agents. The oil phase, which accounts for over 8O% of the chemical cost of the procedure, could largely be recycled by filtering, standing, and layering. The whole procedure is suitable for application as an industrial process.展开更多
