问题 问答题

某城市根据当地资源及社会经济发展的需要,拟规划一工业开发区,以能源重化工为主,规划用地面积10km2,现委托你所在机构进行该工业园区规划的环境影响评价。该城北部以一条河流与另一城市相隔,该河流为两城市的饮用水源。该城西南方向有较大面积的农田,且均为基本农田,农田西南有山脉一处,为国家级森林公园。根据城市发展规划,城市在未来十年内将由现在的30万人口发展到45万人,城市总体发展方向为沿江向东西两个方向展开。近期拟建设污水处理厂一座,位于城市东南方向16km处,用于处理城市污水和部分工业废水,处理后的污水尽可能作为中水回用,少量排入北部河流城市下游段。在城市规划中预留了三处工业开发区,分别为城市东东南方向15km处(A区)、东南方向20km处(B区)、南东南方向17km处(C区),分别发展能源重化工业、轻工纺织业和机械加工业,但未明确哪一区块用于发展能源重化工业。三处工业区规划实施需搬迁9个村庄近10000人。开发区集中配套建设相应的供水、供电、交通和通信设施。该区域常年主导风向为西北风,春季常有来自西北方向的大风,年降水量560mm,蒸发量4300mm,冬季较为寒冷。
