天津滨海盐土的脱盐碱化及其防治

天津滨海盐土在长期治理过程中由于盐土的脱盐碱化，以及缺少有机肥料和低矿化（高钠）碱性水灌溉等原因，已出现了程度不等的碱化土壤。试验表明，应用有机无机改土剂和增施有机肥、深耕深翻、咸淡水混合灌溉等农艺措施，并与工程措施、生物措施相结合进行综合治理，能收到明显的改良效果。

Biological and socioeconomic implications of recreational boat fishing for the management of fishery resources in the marine reserve of Cap de Creus (NW Mediterranean)

A survey of coastal recreational boat fishing was conducted in summer 2006 in the marine reserve of Cap de Creus (NW Mediterranean) to assess the biological and socioeconomic implications of this leisure activity. Recreational boat fishers employ four different fishing techniques: bottom fishing rod, fluixa, trolling and surface fishing rod. Although the targeted species depend on the fishing method used, a total of 33 fish species were identified in the catch (8 were pelagic or benthopelagic and the rest were demersal). Fishing effort was high since fishers fished an average of 4 h/day, 8 days/month and nearly 6 months/year. Apart from the highly varied exploitation of the fauna, recreational fishing in Cap de Creus has a large economic effect on the local economy since the majority of fishers were visitors who were spending holidays in one of the villages belonging to the Park, where most of expenditures related to angling activities were made. Overall, results highlight the pressure that recreational boat fishing exerts on fish communities, particularly on littoral, demersal ones. Considering these biological and socioeconomic implications, the competition between recreational and artisanal fishers for littoral resources and the low level of compliance with the current sport fishing regulations, the implementation of a comprehensive management strategy in Mediterranean costal areas is needed.     

Reconstructing 100-150 years of logging history in coastal spruce forest (Picea abies) with special conservation values in central Norway

Coastal spruce forests of central Norway harbour a unique assemblage of epiphytic lichens and are given high priority with respect to conservation of biodiversity. To assess the historical impact of logging during the last 100-150 yrs, 31 remnant stands were studied by means of tree-ring analysis of 2199 trees and the decay stage of 1605 stumps. No stands had been clear-cut, but all had been selectively logged at least twice during the last 150 yrs. Total harvested timber volume ranged from 65 to 409 m³ha-¹ (31-124% of present-day standing volume) and the selective logging kept standing volume low (40-200 m³ha-¹) during 1890-1930. Present-day stand characteristics were strongly correlated with site productivity and topographic position within the ravine valleys. Low amounts of dead wood at sites with high historical logging activity was the only consistent relationship found after covariance of site productivity, topographic position and deciduous trees were taken into account. The results indicate that old-growth stand characteristics, such as reversed J-shaped age distributions and dead wood in advanced decay classes, can be obtained 100-150 yrs after intensive selective logging.     

木麻黄海岸林林下套种技术与综合效益探讨

以福建泉州木麻黄海岸林为研究对象,探讨了木麻黄林下套种技术以及林下套种植被的生长效果和综合效益。经实践证明,木麻黄海岸林林下套种技术能够提高海岸土地资源的利用效率,降低风速,提高林分生产力和综合防护能力,因此值得进行深入研究和推广。     

威海伴月湾公园景观规划设计

在城市化水平日益增长的今天,人们已经意识到城市生态环境建设的重要性,沿海城市均有公园建设和港湾绿地的营造,那么如何构建与城市自身相和谐的滨海公园,如何营造和谐港湾,将是一个盛行不衰的话题。本文以威海伴月湾公园景观规划设计为例,来诠释这一相关问题。     

环境因子对胶南沿海防护林土壤呼吸的影响

对胶南沿海防护林灌草带和混交林的土壤呼吸速率及其环境因子进行了研究，结果表明：两个类型林地的土壤呼吸速率日变化均呈现出单峰式的变化规律；地表温度是影响土壤呼吸速率的最关键因子，与两个类型的土壤呼吸速率都呈极显著正相关关系，相关系数分别是0．958、0．980；气温也是影响土壤呼吸速率的重要因素，与灌草带土壤呼吸速率呈显著正相关，相关系数是0．857；大气温度、土壤湿度和风速对土壤呼吸速率都有一定影响，但不显著，其中风速对土壤呼吸的影响有待于进一步研究。通过逐步回归方法，得出海防林土壤呼吸速率的主要环境因子与土壤呼吸速率之间的回归模型。
