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.
