尾叶桉、巨桉优树选择标准的建立

尾叶桉、巨桉是华南地区引种成功及重点改良的2种桉树,以往选优基本上是围绕短周期纸浆纤维材改良目标而进行,选优林分的林龄小于15 a,多为6 a以下。本文以林龄16 a以上的尾叶桉、巨桉林分进行选优,以期为中大径材桉树培育提供改良用的优树材料。采用三株优势木对比法和配对T检验法确定优树生长量临界值,并兼顾干形质量指标进行选优。通过对25株候选优树和75株优势木生长量、分枝与干形分值的分析,建立了尾叶桉、巨桉优树选择标准：优树的单株材积≥3株优势木平均单株材积的1.35倍,胸径≥3株优势木平均胸径的1.15倍或树高≥3株优势木平均树高的1.03倍,分枝＋干形得分≥7。在候选的25株优树中有17株符合标准被评为优树,入选率为68%。

WebPIPA （Web Based Paddy Irrigation Productivity Assessment）： An Online Irrigation Water Supply Management for Tanjung Karang Rice Irrigation Scheme （TAKRIS）

Irrigation water management has significant economic implications in developing countries like Malaysia. As in many countries, Malaysia is also espousing internet as a platform of new possibilities for information access and sharing. Thus web based decision tools are pertinent in managing water, which is becoming a source of conflict between domestic, industry and agricultural use in this emerging technological and information age. Decision Support System （DSS） created in the past was theoretically acceptable but practically not effective in the transfer of scientific knowledge from research labs to the end-users to support them in decision making. The Web Based Paddy Irrigation Productivity Assessment （WebPIPA） is an example of DSS created to provide an effective conduit for the transfer of scientific knowledge from research labs to the end-users to support them in decision making. WebPIPA serves as an innovative, user friendly and efficient management tool for run-of-river rice irrigation system. It is a web based program that requires users to login through user name and password WebPIPA is developed using Net framework and ASP. Net Programming Languages of Microsoft. Net 2003 environment. A 3-tier architecture framework was carefully studied and was implemented to create the WebP1PA model. Mathematical model developed for aiding irrigation decisions must be oriented towards addressing various issues in addition to the scientific ones for better acceptability. All government and private agencies, researchers, station users, farmers, investors and buyers related to this study area will be able to access and share the database through the internet. By strengthening the involvement of government departments, the database can be very effectively used by all stakeholders at the same time narrowing the gap between the urban and rural communities in the development of country.     

福建省马尾松优树自由授粉子代变异及其分析

对１０年生马尾松优树自由授粉子代的树高、胸径、材积和通直度性状变异的研究结果表明，２６３个优树家系中有２６．６２％材积生长超过对照１０％以上．其中龙岩地区优树的子代生长表现最佳．同地区不同林分的优树子代有很大差异，林分间平均变异系数大于林分内家系间的平均变异系数．在不同海拔林分选择的优树，除戴云山南麓海拔６００～７００ｍ左右优树子代生长表现较好外，其它海拔点的子代无明显差异，且都差于对照．优树子代生长性状与树干通直度之间存在显著正相关，表明可望同时在生长性状和干形上得到改良

Soil and sediments listservers

Internet listservers, a freely available resource on the Internet for anyone who can send and receive emails, provide a means for professionals to communicate and collaborate with each other in the field of soils and sediments. While moderated listservers are highly effective, in terms of quality and participation (activity) level, do not underestimate the knowledge base held within many of the soil and sediment-related listservers. Readers are encouraged to subscribe to those lists which match their own areas of the soil and sediment fields and to become active. Currently, the only listservers dedicated to sediments are of very low activity, with the lowest numbers of subscribers of all listservers surveyed. As a word of caution, Internet listservers are not a primary source of knowledge (in any scientific field), the quality of knowledge exchanged is highly variable, and if not properly managed, can waste time.
