How to further improve the quality of plan environmental impact assessment of power grid during the "14^(th) Five-Year Plan" period is very important. In this paper,the plan environmental impact assessment of power grid in the Development Plan for Power Grid in Nanjing during the "13^(th) Five-Year Plan" Period is studied to further discuss the ideas,evaluation system and content framework of plan environmental impact assessment of power grid.展开更多

In the past two decades, especially in recent years, much more importance has been attached to Strategic Environmental Assessment. The Environmental Impact Assessment Law of the P.R. China which was promulgated provides a great opportunity for the development of Planning Environmental Impact Assessment and brings great challenges for the development of traditional Project Environmental Impact Assessment and Planning Environmental Impact Assessment at the same time. In order to promote the implementation of "The EIA Law", the inherent limitations of Project Environmental Impact Assessment must be identified sufficiently and the theory research and practice of Planning Environmental Impact Assessment should be strengthened as well. Measures should be taken currently to enforce the operation system. The authors wish to offer a few references to the progress and implementation of Planning Environmental Impact Assessment in China.展开更多

Here, the work carried out in Wuhan was reviewed, combined with the new requirements of the current ecological civilization construction in Wuhan City, and the framework, the key technical points and the important focuses of the carrying out of the tracking evaluation of planning environmental impact assessment were proposed.展开更多

Methods: Eleven patients with NSCLC, who were treated with three-dimensional con-formal radiation therapy, were studied. Each patient underwent twice sequential planning CT scan, i.e., at pre-treatment, and at mid-treatment for field reduction planning. Three treatment plans were established in each patient: treatment plan A was based on the pre-treatment planning CT scans for the first course of treatment, plan B on the mid-treatment planning CT scans for the second course of treatment, and treatment plan F on the fused images for the whole treatment. The irradiation doses received by organs at risk in the whole treatment with treatment A and B plans were estimated by the plus of the parameters in treatment plan A and B, assuming that the parameters involve the different tissues (i.e. V20=AV20+BV20), or the same tissues within an organ (i.e. Dmax=ADmax+BDmax). The assessment parameters in the treatment plan F were calculated on the basis of the DVH of the whole treatment. Then the above assessment results were compared. Results: There were marked differ-ences between the assessment results derived from the plus of assessment parameters in treatment plan A and B, and the ones derived from treatment plan F. Conclusion: When a treatment plan is altered during the course of radiation treatment, image fusion technique should be performed in the establishment of a new one. The estimation of the assessment parameters for the whole treatment with treatment plan A and B by simple plus, is inaccurate.展开更多

Chinese government promulgated the Environmental Impact Assessment Law of China (hereinafter referred to as the EIA Law) in 2002. In this law, it is stipulated clearly that regional and sector plans should be assessed. Through investigating materials and analyzing literatures, this article analyses the practical and academic study achievements of SEA in China that have been achieved since the EIA Law was implemented, probes into the current situation of the main level of SEA in China-plan EIA, then summarizes the development characteristics, and eventually, puts forward the development trends of SEA in China. The research conclusions can offer the foundations for comprehending systematically the progress of SEA in China.展开更多

On the one hand, plan EIA should be promoted further in all industries; on the other hand, the current achievements and methods of plan EIA should be summarized and innovated. And the EIA supervision and project access can be improved further through the coordination between plan EIA and project EIA. In this study, from the three levels of plan EIA policy framework, five problems of plan EIA in power sector were analyzed according to the current situation of plan EIA in power sector. Based on the present achievements, five macroscopic suggestions were proposed from the view of innovation accord- ing to the new environmental protection situation and requirements at present.展开更多
