中国发展沙产业的技术经济约束分析

Technological and Economic Development Constraints in the Chinese Sand Industry

作为兼顾生态建设和经济发展的重要手段，沙产业在我国北方发展迅速。但由于对产业的特殊性认识不够，产业发展缺少规划、缺少资金和缺少扶持，许多地区的沙产业蜕变成新一轮的开荒，给大范围的生态带来了隐患。建议各级地方政府按照《防沙治沙法》，将生态恢复作为产业发展的首位目标，做好规划和总量控制，因地制宜进行政策扶持，使产业发展与国家生态建设工程形成互促机制。

The sand industry is developing rapidly in northern China as an important ecological means of construction and economic development. However, the peculiarity of sand industry has not attracted enough importance to date, which has in there are three basic scarcities for the industry： planning, funding and assistance. As a consequence, many production facilities have changed to “land reclamation” areas, bringing latent ecological peril. It has been suggested that local government should regard ecological restoration as the first goal of sand industry whereby industry planning can be undertaken according to the principle of “Topcap control of water resources”, then give financial and other support according to the principle of “suit measures to local conditions”, and make the industry＇s development a national ecological construction project that forms a mutual benefit system.
