吉安樟筒天牛的空间分布型

为了探索经济有效的控制吉安樟筒天牛Oberea sp.的方法,对其进行了空间分布型的调查。吉安樟筒天牛适合尼曼分布,亦即核心分布,且虫口越大越明显。在治理上针对核心进行挑治,不仅可以节省人力、物力和财力,减少化学农药对环境的污染,还有益于樟树林内昆虫自然生态系统的稳定。

黄柏瘦筒天牛生物学特性及其防治

瘦筒天牛Oberea atropunctata Pic是黄柏Phellodendron chinense Schneid的重要枝干害虫之一，在贵州黔南地区1a发生1代，以幼虫在蛀道内越冬。幼虫蛀食黄柏枝条，成虫取食嫩叶、嫩梢或叶脉皮层。寄主仅发现黄柏1种。该文还提出了瘦筒天牛的防治方法。

FORESTAR：A decision—support system for multi—objective forest management in Northeast China

Past monoculture forestry in China has contributed to countrywide ecological disasters and economic difficulties in forestry regions. China‘s new forestry programs, Natural Forest Conservation Program and Returning Farmlands to Forests Program, provide opportunities for ecosystem management of mountain forests in China. A decision support system, FORE-STAR, has been developed for better managing and protecting natural forests in Changbai Mountain area. It uses GIS-based forest inventory data at a scale of forestry bureau. The first version contains two sub-modules: forest operation and forest res-toration. Under each sub-module, users can compare several decision options and make optimal choices. It can help field for-esters, forest managers, and policy makers make multi-objective and consistent decisions in planning forest management at hierarchical administrative scales.     

Research trends: Policy impact evaluation: Future contributions from economics

Economic research has become more empirical, and much of the shift has been due to the broad applications of impact evaluation (or IE) methods for measuring the potential effects of policies or programs on outcomes of interest. The objective of this article is to introduce the essential IE methodology and literature to the audience of this journal and discuss how we can take advantage of these research developments to improve the quality of our own work and subsequent publications. Following an overview of the core IE concepts and methods, we will give an overview of the recent uses of these methods to address forest policy issues and outline the basic steps of sampling and data generation involved in an IE study.     

Planted forests: poplars

Poplars (Populus spp.) have been planted in Europe and Asia since very early times. Known in the Near East as the blessed tree, poplars have been the primary timber producer in regions lacking natural forests in the northern hemisphere. Now, though, we are seeing poplar plantations becoming part of the forest resources even in the abundantly forested Pacific Northwest. Though still a minor contributor to the world's timber supply, the area of land planted to poplars is, nevertheless, increasing rapidly, particularly in China, South Korea, and the United States. The 1992 report from the International Poplar Commission listed nineteen countries with at least 10,000 ha of planted poplars and seven with more than 100,000 ha. Much of the success of poplar plantations results from the breeding of fast-growing and disease-resistant poplar hybrids. Accordingly, at least eleven countries support poplar breeding programs. Uses of poplar wood range from peeled poles for rafters and other elements of construction in agrarian economies to the manufacture of paper, plywood, oriented strand board, and engineered lumber in industrial nations. Interest has also developed in poplar plantations as a renewable source of energy.     

基于Kano模型的森林公园环境教育需求分析研究——以开封市康平河森林公园为例

本研究以开封市康平河森林公园为例，分析游客环境教育需求，为城市公园环境教育功能的实现提供参考。通过问卷调查、Kano模型与Better-Worse系数法对公园进行需求类型调查、重要程度排序与人群差异化分析。研究表明在五类一级需求中需求重要度依次为设施需求、工作人员需求、教学形式需求、费用需求、活动内容需求，在游客需求差异化分析中园内设施与活动内容需求差异最明显。得出以下结论：应对公园设施进行合理规划；增设咨询服务点及解说设施；设置多种形式的环境教育活动；增设环境教育相关人员岗位并做好培训；注重差异化设计。
