摘要:

土地利用规划的实施对区域环境有着长期、复杂、综合的影响,有时这种影响甚至是不可逆的,这就需要对规划实施可能导致的环境影响进行科学分析,以实现对土地资源的优化配置。然而在目前,国内开展的环境影响评价大多围绕建设项目进行,涉及规划环境影响评价的理论和实践还比较缺乏。立足于实际所需,以县级土地利用规划为例,对其环境影响评价的流程和方法进行了全面设计,按照时间先后划分为回顾性评价和预测性评价两类,并分别采用加权求和法和神经网络法进行分析,同时以金口河区作为研究对象进行了具体应用,结果表明该方法简便适用、易于理解,能够对土地利用规划实施所造成的环境影响进行比较客观、准确的分析。当前,新一轮土地利用规划修编工作正在各地陆续进行,研究成果能够为实际的规划环评工作提供一些具体的方法指导。

Abstract:

It needs to carry on scientific analysis in order to realize the optimum allocation of land resources because the implementation of land use planning has a long,complicated,comprehensive,and sometimes irreversible effect on the regional environment.So far,environment impact assessment is mostly around the construction projects but less in the planning.In terms of the practical demand,the study discussed the overall design of evaluation process of land use planning at county level.According to time,it was divided into two types of retrospective assessment and predictive assessment which was analyzed using weighted summation method and artificial neural network separately.Then,taking Jinkouhe area as an example,the results show the evaluation method has advantages of convenient,applicative and understandable,and it can analyze the environment impact objectively and accurately. At present, the new general land use planning is carrying out gradually throughout the country,and the research achievements can provide some specific guidance for the actual planning environment assessment practice.
