Potential production simulation and optimal nutrient management of two hybrid rice varieties in Jinhua,Zhejiang Province,China

Potential growth of two widely-grown hybrid rice varieties in the Jinhua district of Zhejiang Province, Shanyou63 for mid-rice and Xieyou46 for late rice, was simulated using a crop growth model of WOFOST. Parameters of the rice growth in WOFOST were calibrated through field experiments from 1999 to 2002 in Jinhua. The potential yield simulated with WOFOST was about 12 t/ha for Shanyou63 and 10 t/ha for Xieyou46, which are in good agreement with the highest recorded yield obtained in this area. Under farmers practice, current yield is about 7.5 t/ha for Shanyou63 and 6.5 t/ha for Xieyou46. There is a gap between the actual rice yield and the potential yield for these two hybrid rice varieties grown in this area. The attainable target yields were set to 70% to 75% of their potential yields for the two varieties. A recently developed software ＂Nutrient Decision Support System （NuDSS）＂ for irrigated rice was used to optimize nutrient management for these two rice varieties. According to NuDSS, the optimal fertilizer N requirement for the target yields was about 150 kg/ha for Shanyou63 and about 120 kg/ha for Xieyou46, which were only about 70% of the fertilizer N application under current farmers＇ practice. Comparing with farmers＇ practice, there is great potential to increase actual rice yields and to reduce fertilizer N use rates by improving rice crop management practice in Jinhua.     

试论环保执法的现实障碍及其法律对策

我国环保执法的现实障碍主要表现在以下几个方面:思想观念的滞后性;环保立法不能完全适应环保执法的现实要求;环保部门的执法权限尚嫌不足,执法手段不够充分;环保执法的民主性和透明度不够;监督机制不强。对此,提出了加强环保法制建设和提高环保执法能力的对策。

ISM-CMAP-Combine (ICMC) for hierarchical knowledge scenario in quality engineering education

Quality assurance in engineering education is a multifaceted problem further augmented by the stakeholders of engineering education. Students, parents and employers are rightfully questioning the quality of the curriculum, the instructional delivery, the learning environment, accessibility to learning technologies and equipment, employability as well as the possibilities of lifelong learning and the improvement of knowledge (Karapetrovic 2002 Karapetrovic, S. 2002. Why and how to develop a meaningful quality assurance system in engineering schools. Int. J. Engg. Educ, 18(3): 285–294. [Web of Science ®] [Google Scholar]). The purpose of the study is, therefore, to identify the parameters that influence the quality of an engineering education system and develop an integrated model of hierarchical structuring and a concept map for pre-identified concept elements through a process of iterative-interactive consensus-driven methodology, as advocated by second-generation system design paradigm for evolving knowledge scenario of concepts related to quality engineering education.     

中国环境保护的难点与破解之道

中国环境保护事业飞速发展,在经济高速增长的同时,环境质量恶化的趋势得以减缓。但由于治理的速度仍赶不上污染的速度,环境形势依然严峻。做好新形势下的环保工作,必须加快环境与经济的融合,加快实现三个转变:一是从重经济增长轻环境保护转变为保护环境与经济增长并重;二是从环境保护滞后于经济发展转变为环境保护和经济发展同步;三是从主要用行政办法保护环境转变为综合运用法律、经济、技术和必要的行政办法解决环境问题。必须在国家战略层面将环境与经济有机结合起来,将环境保护的要求渗透到产业政策、货币政策、价格政策、财税政策和贸易政策之中,以环境友好的政策确保发展战略的顺利实施;将环境保护的领域由以生产为主,拓展到消费、分配、流通的各个环节,形成覆盖再生产全过程的环境管理体系;坚持从经济全球化的战略高度驾驭环境保护。
