桐麦间作人工群落空间分布格局的灰色局势决策

本文采用多目标灰色局势决策的方法，以桐麦间作人工群落为例，以１０年为泡桐生长的一个轮伐期，以６种不同的空间配置方式作为对策，以林业经济收益、农业经济收益和系统总体效益为目标，进行多目标决策，定量研究其空间分布格局。研究结果表明，以农为主间作型泡桐的最佳株行距为５×４０ｍ，以桐为主间作型的为５×５ｍ，农桐并重间作型的为５×２０ｍ。

How Community Action, Science and Common Sense can Work Together to Develop an Alternative Way to Combat Desertification

The Spitzkoppe Community Campsite in western Namibia lies in an area with very limited water resources. Water scarcity places a constraint on community income generation and development opportunities. The existing water resources are overexploited and to ensure future water security, the community must take sustainable water management into consideration in their daily lives and business ventures, including tourism. This has been successfully achieved at the Spitzkoppe Community Campsite through a combination of high community motivation, organisation and action, the involvement of researchers and trainers in water resource management and support from developers. The most appropriate water management solutions were found through ongoing practical testing of different strategies and technologies over two years. This paper presents a case study of a community-based tourist camp at Spitzkoppe and traces the community’s progress towards developing an alternative way to combat desertification and a potentially lucrative tourist business.

A comparison of fixed-site and non-fixed-site approaches for species protection

The efficacy of simultaneously advancing two distinct conceptual designs (referred to here as fixed-site and non-fixed-site) for species conservation and protection is addressed. In the literature, numerous models can be found that typically stem from a particular design, but rarely are comparisons made between approaches. This paper presents a more integrated optimization framework that models landowner behavior and species viabilities at a landscape scale. Regional demand for resource extraction is used as the economic driver, a variant of simulated annealing is used to solve the model under different species protection approaches, and a detailed species population simulator is utilized to measure biological responses. When directly comparing the outcomes of different species protection strategies from a case study in Oregon (USA), it was found that neither approach was universally superior in terms of financial value or degree of protection for two late seral forest dependent species.
