为合理利用和科学消纳工程建设弃方,实现自然资本的保值增值,基于三维地理信息环境,将GIS技术、勘察信息大数据引入到山地城市工程建设土石方管理中来,提出了科学的工程建设弃方处置方法；采用实地观察法、文献调查法、访谈调查法等方法,提出了土石方资源化利用途径及方法,实现了将传统工程产生的土石方弃方资源化利用,变“废”为宝。并以重庆市北碚区为例,在国土空间规划编制中,开展了土石方资源化利用专项规划探索实践,对土石方资源化分类和价值效益进行分析,结合矿坑生态修复进行存储场地选址规划,发挥国土空间规划对项目落地的指导约束和保障作用,实现土石方资源集约高效利用。

In order to rationally utilize and scientifically absorb the abandoned area of engineering construction and realize the preservation and appreciation of natural capital, GIS technology and big data of survey information are introduced into the management of soil and rock of engineering construction in mountainous cities based on three-dimensional geographic information environment, and a scientific method of disposal of abandoned area of engineering construction is proposed. Using the methods of field observation, literature investigation and interview investigation, this paper puts forward the ways and methods of earth and rock resource utilization, realizing the resource utilization of earth and rock waste generated by traditional engineering and turning "waste" into treasure. Taking Beibei District of Chongqing City as an example, in the preparation of territorial spatial planning, we carry out the exploration and practice of the special planning of the resource utilization of earth and stone, analyze the classification and value and benefit of the resource utilization of earth and stone, and plan the site selection of the storage site in combination with the ecological restoration of the mine, so as to give full play to the role of territorial spatial planning in guiding, restricting and guaranteeing the implementation of the project, and realize the intensive and efficient use of earth and stone resources.
