Comparison of two coniferous plantations in central Japan with respect to forest productivity, growth phenology and soil nitrogen dynamics

Japanese cypress (Chamaecyparis obtusa Endl.) and Japanese cedar (Cryptomeria japonica D. Don) are common species for plantation forestry in Japan. Cypress is conventionally planted on sites of low fertility whereas for cedar high fertility sites are used. Objectives of this study were to compare the productivities of cypress and cedar plantations grown on adjacent sites where common properties of soils, such as pH values and C and N contents, were similar, and to relate the N cycling at their site with productivities. The stem diameter of trees, aboveground litter production and fine root biomass were measured as indices of forest productivity. Parameters of N cycling included pools of total N and mineral N (ammonium + nitrate), annual N leaching, and potentially mineralizable N. The radial stem increment of the two tree species was similar. However, cedar site had higher total basal area and annual basal increment than cypress site reflecting higher tree density on the cedar site. Aboveground litter, fine root biomass, soil organic matter, and N turnover were higher on the cedar site than on the cypress site. However, litter production and fine root biomass per unit basal area was greater at the cypress site. Phenological pattern of stem growth and periodical litter production were similar for both species during the study period (1992–2000), but showed distinct annual variations caused by the fluctuation in the ambient temperature and precipitation. Mineral N content and the N mineralization potential were greater on the cedar site, indicating greater N availability and higher total tree productivity at the cedar site than those at the cypress site. When provided with more space in the canopy to expand more needles and in the soil to develop more fine roots to exploit sufficient resources, the individual cypress trees have the potential to grow faster. On fertile site and at lower tree density, thicker logs of cypress might be yielded.     

应用遥感数据识别意大利沿海松林灾害级别

分析了LandsatTM和ERS-1SAR数据用于识别意大利沿海松林污染灾害级别的潜在能力，结果显示出夏季获取的TM数据在森林灾害制图上远比冬季获取的TM数据和SAR影像有效，但SAR影像的贡献也是不可忽略的，文中给出了应用人工神经元网络B-P模型得到的对意大利沿海松林污染灾害级别划分的结果和应用FINDKAPP程序得到的精度评价结果。

林业应为江西在中部地区崛起提供强大支撑--"江西在中部地区崛起,林业的定位和作为"研究报告

林业是经济和社会可持续发展的重要基础,是生态建设最根本最长期的措施。江西在中部地区崛赶,应赋予林业以重要地位。在江西的产业结构调整中,确立了建设“三个基地,一个后花团”的发展战略,林业应为此提供强大支撑。在研究我国中部地区及东部邻省林业发展经验及优势产业比较的基础上,按照我国林业历史性转变的指导思想,提出了“确立以生态建设为主的林业可持续发展的定位和作为”。
