摘 要:广东省四会市的土地自然侵蚀主要分布在山区和丘陵区,以面蚀为主。人为侵蚀类型主要包括陡坡开荒、采石取土,侵蚀强度从中度到剧烈均存在,侵蚀情况较为严重,且取土采石造成大面积高强度的侵蚀。水土保持监测是水土保持方案实施的重要环节,也是水土保持防治的有效措施之一,为解决实施监测中的实际问题,本文结合工程实例作简单阐述。

Abstract: Sihui City, Guangdong Province, the land of natural erosion mainly in mountainous and hilly areas to surface erosion based. Types include anthropogenic erosion on steep slopes, land reclamation, quarrying earth, from moderate to severe erosion intensity are present, the situation is more serious erosion and quarrying causing widespread soil erosion of high intensity. Soil and water conservation and water conservation monitoring is an important part of implementation of the program, but also one of the effective prevention and control soil and water conservation, to solve practical problems in the implementation of monitoring, this paper briefly describes engineering examples.

1.前言

廣东省是我国建筑用石料的消费大省,建筑用石料产量连续多年位居全国第二,总产量约占全国石料产量的10%。广东的石料市场一直以强劲的需求不断地扩展,珠江三角洲地区建筑石料市场需求旺盛。

广东省四会市东城街道前进矿区工程项目位于广东省四会市城区80?方位、直距约7km处,行政隶属四会市东城街道办事处管辖。矿区中心地理坐标:东经112°46′21″,北纬23°21′12″。矿区至四会市城区约10km,至大旺开发区专用码头运距约15km。四会市通过广贺高速公路、水路、G321和G324国道可达全国各地,交通条件便利。项目建设区53.73hm2,总体划分为采矿区、矿山道路区、办公生活区、破碎堆料区、设计排土场共5个水土流失防治区。

矿区范围下游800m外有大片农田和多个鱼塘,由于矿区上游坡面汇集来水大部分汇集至矿坑内,其余可通过附近山溪自流排放,采石活动集中于采矿区范围内,所造成的水土流失不对坑外的环境造成直接影响。

降雨是决定侵蚀强度的主要水文……
