社区对自然资源的破坏性利用是中国自然保护区有效管理的最大威胁,而如何有效规范社区对自然资源的利用则是自然保护区有效管理面临的最大挑战。如果市场需求与市场供给之间没有建立起有利于生态保护的联动机制,市场驱动不仅不能规范社区对自然资源的利用,反而刺激社区对自然资源的破坏性利用。"基于社区组织与市场驱动的自然保护区管理方法"就是在自然保护区管理部门的协助下,以生态友好型产品的市场需求为驱动力,通过组建运行类似农民专业合作社、社区自然资源管理小组的社区组织,在市场需求方(产品消费者)和市场供给方(产品生产者或自然资源采集者)之间建立起有利于生态保护的联动机制,规范社区对自然保护区内或周边自然资源的利用,从而改善自然保护区的有效管理。该方法主要由四个要素构成:社区生计对自然资源的高度依赖性、具备社区经济发展和生态保护功能的社区组织、生态友好型市场驱动力以及自然保护区管理部门的协助能力。社区赋权、市场化、透明性、公正性等是该方法的基本原则。

管理计划是保护区有效管理的重要手段,越来越多的保护区在编制或更新自己的管理计划,但也出现了许多问题,包括重文本轻实用、重专家主导轻关键利益相关者参与、重复制轻创新等,尤其是严重缺乏编制管理计划的能力,包括缺乏针对保护目标与保护特点识别、现状分析、问题分析、对策分析、优先管理对象识别、融资、监测评价指标体系开发(逻辑框架)以及特色创新等。为此,建议保护区管理部门要重视管理计划编制能力建设,重视关键利益相关者尤其是社区的参与,在生态系统层面确定保护目标和管理目标,并构建管理计划实施绩效的监测评价指标体系,确保国家的财政投入产生应有的保护绩效。

计算机控制光学表面技术(CCOS)是加工光学非球面的一项重要技术。在计算机控制小磨头抛光技术中,边缘效应严重制约了CCOS技术的加工精度和加工效率,是亟待解决的技术难点之一。获得磨头在加工工件边缘时的定量去除模型,并通过驻留时间算法进行补偿,是解决该问题的重要途径。采用边缘压强阶跃分布模型,并通过理论推导,得出边缘效应下的去除函数计算模型。去除函数实验的结果表明,该边缘去除函数计算模型的数值绝对误差在5%内,边缘去除函数模型与实际加工吻合很好,可以用于指导实际抛光过程。

社区发展在自然保护区有效管理中扮演着越来越普遍和重要的角色,但现有的社区发展项目从规划到实施都存在严重缺陷,特别是缺乏对自然保护区有效管理的直接贡献,更没有实现机制化。以自然保护区有效管理为前提的社区发展行动必须以直接贡献自然保护区的有效管理为首要目标,将社区发展作为实现这个目标的机制化手段之一而不是单纯的脱贫项目,并通过这个过程逐渐建立保护与发展相互促进的机制和能力,使自然保护区的有效管理同时能够直接贡献当地社区和地方经济的发展。
