Agricultural land use in the coastal area of the Alexander von Humboldt National Park, Cuba and its implication for conservation and sustainability

In the Alexander von Humboldt National Park in eastern Cuba many endemic animals and plants are found in various different natural habitats, which are considered to be the most important ones for in-situ conservation in the entire Insular Caribbean. In some areas of the National Park agriculture is practised. Thus, the objective of this study was to document and analyse the different land use activities and their consequences for local resource management and conservation of biodiversity in two village areas. A particular question was: what has changed since the foundation of the National Park in 1996? As time series data for land use and aerial photographs were not available for this part of Cuba, a qualitative evaluation was carried out. For this, six different land use units were mapped in 2001 and additional information gathered for areas with special interest related to sustainable land use and resource conservation. Although most parts of the study area are influenced to various degrees by human impact, the different types of land use seem presently not to have a crucial or detrimental impact on the land resources of the Alexander von Humboldt National Park. However, exploitation of the natural resources in certain areas could be improved with different management options to reach sustainability as well as to meet the conservation objectives of the National Park. This includes reduced or abandoned agricultural use of steep slopes to reduce erosion risk as well as a facilitated regeneration of natural vegetation in many parts of the study area to be able to conserve the high valuable biodiversity of the Park. Environmental education seems to have played an important and successful role since the foundation of the Park in 1996. Since then, cropping on steep slopes as well as illegal logging and poaching could be reduced.     

鲁中南岩溶水资源综合类型及合理调蓄研究

鲁中南岩溶区是中国北方半干旱温带岩溶区中具有代表性的地区之一。该区岩水资源分布具有明显的不均匀性和大面积分散补给而局部富集等特征。岩溶形态以溶蚀裂隙洞穴为主，地下水类型多为裂隙溶洞型。在对该区岩溶水补给，富集，径流及排泄特征的研究基础上，初步将本区地表水和地下水资源划分为两大类型，即地下岩溶水径带变化带水资源类型和排泄带水资源及地下岩溶水资源类型。对该地区地表水和地下水的合理调蓄问题进行了系统的分析和总结，并提出了相关的对策。     

21世纪黄河系统工程方略

该文指出 :王化云的治黄思想 ,“上拦下排、两岸分滞、蓄水拦沙、宽河固堤、除害兴利、综合利用” ,实际上是治理黄河的系统工程 ,2 1世纪应该继承和发展黄河系统工程的方略。黄河地处中国腹地 ,是中华民族的摇篮 ,当今高新科技的发展 ,足以从更大的范围 ,以全国的水资源、土资源为核心来考虑黄河的建设。统一计算水资源中的大气水、地表水、地下水、壤中水、生态水、环境水、生产水、生活水 ;统一计算土资源中的土壤资源、沙资源、沙石资源 ,真正按照地理系统工程来建设黄河。

论世界及我国火山旅游资源的开发利用

世界火山分布具有规律性。火山旅游资源具有广泛性和高品味性。火山旅游资源的开发利用需要具有科学的态度和综合性的手段。世界许多国家开发利用火山旅游资源的经济值得我们借鉴。     

资源环境与社会经济协调发展探析

文章首先回顾了资源环境与社会经济发展的理论，提出资源环境与社会经济协调发展内涵：一方面，要在资源环境承载力范围内发展社会经济，追求社会经济发展的最大化，另一方面，环境承载力是动态的，要依靠社会经济发展不断提高，这两个方面是相互作用、相互制约的。在此基础上，详细论述了资源环境与社会经济协调发展的内容,并从社会经济发展、资源环境管理等角度探讨了资源环境与社会经济协调发展的政策调控，通过建立节约型国民经济体系、深化资源环境管理，实现区域一体化，以保证资源环境与社会经济协调发展的实现。     

Economic Filters Applied to Quantitative Mineral Resource Simulations

The U.S. Geological Survey has developed a technique that allows mineral resource experts to apply economic filters to estimates of undiscovered mineral resources. This technique builds on previous work that developed quantitative methods for mineral resource assessments. A Monte-Carlo calculation uses mineral deposit models to estimate commodity grades and tonnages of undiscovered deposits. The results then are analyzed using simple estimates of capital expenditures and daily operating costs for a mine and associated mill. The daily operating costs and the value of the ore are used to calculate the net present value of the deposit, which is compared to the capital expenditures to determine whether the deposit is economic. Repetition of these calculations for many deposits produces a table that can be interpreted in terms of the probability of there being deposits that have anet present value exceeding some specified amount. Sample calculations indicate that applying economic filters to simulated mineral resources might change the perception of the results compared to presenting the calculations in terms of the expected mean gross-in-place value of the minerals.
