【摘要】：因为修订不及时、规定不详细等种种原因,中国对河流型水源保护区划分的法律体系在执行过程中尚存在如下一些问题:对一级保护区水域的长度难以通过计算方法确定,对二级保护区水域长度的计算结果偏大,准保护区缺乏相关规定,技术规范与新修订的法律相冲突。对此,需要明确要求划定准保护区并在准保护区内"禁增"污染源,在行政区边界交接断面要求优于地表水Ⅲ类水质标准进行交接,对划分保护区的技术规范进行修改,一级保护区水域长度可以由经验类比法划定,二级保护区水域长度根据一级保护区水质满足Ⅱ类水质标准的要求,在保护区内排污口拆除、准保护区排污不新增的情景下进行推算。按照上述修订建议建立起来的"一级保护区、二级保护区、准保护区和行政区边界"4个层次的水源河流保护区划体系是更合适、更有效的体系。以广东省F市S区D河为例,进行了水源保护区划定。
[Abstract]:Because the revision is not timely and the regulations are not detailed, there are still some problems in the implementation of China's legal system for the division of river water source protection areas: it is difficult to determine the length of the waters of the first class protected areas by means of calculation.The calculation result of the water area length of the secondary protected area is too large, the quasi-protected area lacks relevant regulations, and the technical specification conflicts with the newly revised law.In order to solve this problem, it is necessary to clearly require the designation of quasi-protected areas and the "prohibition" of pollution sources in the quasi-protected areas, and the need for the handover of cross-section at the boundary of the administrative region to be superior to that of surface water quality standards, and to modify the technical specifications for the division of protected areas.The length of the water area of the first class protected area can be determined by empirical analogy method.In the case of no new sewage discharge in the quasi-protected area, the calculation is carried out.It is more suitable and effective to establish the water source river protection regionalization system at the four levels of "the first class protected area, the second class protected area, the quasi-protected area and the administrative district boundary" according to the above revision proposal.Taking D River in S District of F City, Guangdong Province as an example, the water source protection area is delimited.
