南江县属巴中市矿产资源大县,已利用的矿种达15种,特别是北部山区由大理石、花岗石长期风化形成的旱砂矿资源极为丰富,蕴藏量达数亿方。近年来由于城镇化步伐加快,大批重点工程的推进,刺激了当地对建筑用砂的需求。同时,为保护巴河源头饮水源,政府对河道实施保护战略,建筑用砂紧缺,旱砂也因此成为备受亲睐的重要资源。这导致了南江县域内杨坝、关坝等东北部一带无序开采旱砂资源现象风起云涌,不但生态环境受到严重破坏,更是严重影响 Nanjiang County is a large mineral resources county of Bazhong City, which has utilized 15 kinds of minerals. In particular, the resources of dry sand mines formed by the long-term weathering of marble and granite in the northern mountains are extremely rich, with reserves of hundreds of millions of cubic meters. In recent years, due to the accelerated pace of urbanization, a large number of key projects to promote stimulating the local demand for construction sand. At the same time, in order to protect the source of drinking water in the Bahe River, the government implemented a protection strategy for the river course and the shortage of construction sand had made it an important source of pro-Lai. This caused the phenomenon of chaotic exploitation of dry sand resources in the northeastern part of Yangba and Guanba in the Nanjiang County area surging, which not only seriously damaged the ecological environment, but also severely affected
