该论文标题是《浙江省开化县林场杉木人工林建设现状及发展对策》，作者郑成忠 ，胡立志等。简述了开化县林场杉木丰产林、杉木普通林、2 代杉木萌芽更新和杉木公益林改造等多种杉木可持续发展模式及其实施的技术措施。针对目前杉木经营中存在的树种结构不合理、采伐利用不及时、生长量下降、低效林比重大、后备资源缺乏和造林措施不合理等问题，提出了今后杉木可持续经营中要控制杉木发展面积、发展杉木中大径材、加大科技推广力度、采用科学营林措施及合理利用杉木公益林等对策。

The paper titled *Current Status of Chinese Fir Plantation Construction and Development Countermeasures in Kaihua Forest Farm, Zhejiang Province* is authored by Zheng Chengzhong, Hu Lizhi, et al. It briefly outlines multiple sustainable development models for Chinese fir, including high-yield Chinese fir plantations, conventional Chinese fir plantations, second-generation Chinese fir sprouting regeneration, and the transformation of Chinese fir ecological public welfare forests, alongside the technical measures implemented for each model. In view of the existing problems in current Chinese fir management, such as unreasonable tree species structure, untimely harvesting and utilization, declining growth increment, high proportion of low-efficiency forests, shortage of reserve resources, and unreasonable afforestation practices, this study proposes countermeasures for the future sustainable management of Chinese fir: controlling the scale of Chinese fir cultivation, developing large- and medium-diameter Chinese fir timber, strengthening the popularization of scientific and technological achievements, adopting scientific forest management measures, and rationally utilizing Chinese fir ecological public welfare forests.
