沙产业实践模式研究

Research on a practical model for the desert- controlling industry

在参考各地不同类型的沙产业实践案例的基础上,结合沙产业基础学科和理论体系,考虑自然环境、人工可控环境和人工全控装置3种环境条件下的生物类型和沙产业发展方向,对沙产业的实践方向进行了系统归纳,总结出三种沙产业实践模式,即自然露地环境适生生物一体化开发模式、人工调控环境下生物新技术开发模式和人工装置中微藻的生产模式。本研究旨在通过对沙产业实践模式的总结,以期为沙产业的健康发展提供理论参考。

This paper aims to bring forward a general review on the development of the concept of the so-called desert-or sand-controlling industry, and a model for or a approach to the best use of the land and energy resources in the desert areas. As is known, China is a country with vast deserts. Such desert, in traditional view, is equivalent to that of desolation and death, whose unique role is to bring disaster and calamity to human beings in a variety of ways. In fact, however, desert is latent with inexhaustible abundant resources, such as climatic resources, mineral resources, energy resources as well as biological resources, some of which are essential for modern society construction. Based on the above-said potential, Dr. Qian Xuesen, the famous Chinese scholar, initiated a study of desert industry. According to Qian, sand industry is a kind of green plant industry, which takes as its ultimate goal the exploration of ways for full use of the above-mentioned riches by means of the most economic consumption of water and the up-to-date technological advancements to bring economic and social prosperity to the barren land areas with modern agricultural production and a new civilization. Based on the study of Qian, this paper has worked out a desert industry theoretical system, consisting of the theory of environmental protection, that of technological exploration, policy management, production management, and profit and benefit evaluation. At the same time, it has also made a investigative summary of the environmental background of such developments with a concise report of the fragile ecosystem and high photosynthetic materials. In addition, a detailed illustration of available technical means has also been provided in the paper, such as ways of solar energy exploitation and approaches to most economic consumption of water sources for higher benefits. By taking into full account the different biological types and development potential of desert industry under the three categories of environmental conditions, that is, Natural Environment, Controlled Environment and Full-Controlled available Means and Devices, a detailed discussion has been given to the three practical modes： the integrated development of suitable organisms in the open fields, up-to-date biotechnical means for development of human-control conditions, artificial micro-algae production. And, finally, it has given a beneficial evaluation of desert industry. With all the above research efforts, further development of the desert industry is expected to promote an all-round ecological, economic and social advance on the way to build our harmonious society.
