对华山风景名胜区管理体制变革的制度分析

本文以华山景区改革开放以来经历的多次体制变革为事实依据 ,经过理论上的辩析和论证 ,提出了这样 3个基本观点 :1.在特定历史条件下景区从公益型管理向经营型管理转变是一种制度进步 ;2 .我国景区在体制改革中应普遍推行统一管理制模式 ;3.现阶段景区在政府行业管制下实行企业化经营可以有效地提高景区投融资能力和促进景区基础设施建设 ,从而保障国家对景区资产的所有权收益。

“一带一路”背景下天山北坡城市群的综合竞争力评价

天山北坡城市群是中国向西开放的重要环节,在“一带一路”中发挥着重要的作用。构建一个具有4个二级指标、14个具体评价指标的综合竞争力评价体系,运用熵值法选取“一带一路”沿线包括天山北坡城市群的4个城市群进行对比分析,针对天山北坡城市群内部各城市的具体指标得分进行聚类分析。得出以下结论：在中国东中西部三地区间的城市发展仍然存在极大的不平衡问题;天山北坡城市群内部各城市之间的发展也存在着极为严重的发展不平衡问题;天山北坡城市群内部综合竞争力较差的城市得益于“西部大开发战略”,其经济发展较为迅速,但是其并没有辐射至城市内的其他领域,导致此类城市除经济竞争力外的其他3个二级指标与其他城市相差较大。     

发展浙西南山区农产品绿色物流的思考

浙西南山区是浙江省经济欠发达地区,素有“九山半水半分田”之称,农村人口占总人口的80％以上．农民经济来源主要依靠农业收入。近年来浙西南山区充分利用其优良自然环境．重视绿色农产品的开发．形成了浙西南山区食用茵、茶叶、高山蔬菜、水果、畜禽等特色和绿色农产品,但由于物流业发展滞后,绿色农产品价值难以实现,农民增收困难。论文结合浙西南区域特征及物流现状,从树立绿色物流观念、“共性资源”投入、物流模式选择、供应链管理、物流人才培养等方面进行了农产品绿色物流的探讨。

Regional erosion risk mapping for decision support: A case study from West Africa

Effective soil and water management strategies require regional-scale assessment of erosion risk in order to locate prioritized area of intervention. Our study focuses on the Atacora mountain and surrounding areas (covering more than 18% of the total land area of Republic of Benin) which face a serious erosion threat despite their ecological and economic importance. To appraise the level of soil erosion risk of large area, we rely on the Instituto Nacional para la Conservación de la Naturaleza (ICONA) erosion model and use data from geographic information system (GIS). The erosion risk model requires four main inputs, namely, information on slope, lithofacies, land use and vegetation cover. The slope layer computed from ASTER digital elevation model (DEM) and the lithofacies layer inferred from digital pedogeological map are combined to draw soil erodibility map. To build soil protection map, we use land use/land cover layer extracted from LANDSAT 7 ETM + images in addition to vegetation cover layer derived from MODIS NDVI product. The final erosion risk map (with a resolution of 1 arc second) is obtained by overlapping erodibility and soil protection maps. We find that 21.8%, 58.5%, and 19.5% of the study area presents very low to low, medium, and high to very high level of erosion risk, respectively. Moreover, our findings are aggregated at the district-level (administrative unit). We observe that erosion risk is more acute in Boukoumbe district. Kerou, Kobli and Natitingou districts are mildly affected by erosion risk, while Kouande, Materi, Pehunco, Tanguieta and Toucountouna districts face a low risk. Ultimately, the proposed erosion risk map can help researchers and decision makers design and implement effective soil and water management interventions in the study area.

Is farming enough in mountain areas? Farm diversification in the Pyrenees

The continuity of farming in mountain areas in Europe is at severe risk and its future faces manifold uncertainties. Mountain farms are immersed in a long-term process of reorganization. Farm diversification plays a prominent role in this process of adjustment and reallocation. However, little work has been done explicitly on the role farm diversification plays in the current structural changes occurring. In order to fill this void, the nature of farm diversification has been examined in the Pyrenees, where four different typologies of farms have been identified: absence of diversification, agricultural diversification, farmland diversification and finally farm labour diversification. These typologies reflect a gradation along which the farm diversification practices are applied to more aspects of the farm household. Throughout this gradation farming is increasingly marginalised. Finally, it is argued that the endorsement of policy measures stimulating farm diversification in mountain regions should be cautiously considered, since there is high risk of encouraging further agricultural abandonment.

A Spatial-Based Decision Support System for wood harvesting management in mountain areas

In this paper, a spatial-based economic model is proposed with the aim of estimating the most likely harvest cost of a forest block in relation to its particular morphological and operating features. This work, which is based on the classical stumpage price assessment method, presents an economic balance of a forest cut, attained by conducting a cost analysis of each logging phase of the different standard harvesting strategies. The study area is in the North-West of Italy, in the Mount Cotolivier forest compartment, in Oulx, Piedmont. The map of the stand structure, which is included in the Oulx Forest Management Plan, was used to locate blocks (areas considered homogeneous according to the stand structure and forest typology) where silvicultural cuts could be scheduled. The feasibility of the selected logging strategies was mapped considering six conditioning factors, of both a topological and a topographic nature. Their influence was weighted by means of a score assignation and integrated in a Multi-Criteria Decision Making procedure. The scores were mathematically combined to calculate a spatial dependent cost-function (Block Exploitation Aptitude, BEA) in which the suitability of each block to be harvested was mapped through a specific strategy. The obtained BEA was then used to estimate the most suitable productivity rate of the harvests of each block. The unitary costs of the strategies were estimated and then compared to find the most profitable one for each block.This model has proved to be effective in generating objective economic results concerning harvest cuts in productive stands in mountainous areas. The proposed methodology simultaneously takes into account different factors and generates feasibility scenarios, in the space domain, for the considered harvesting strategies. The proposed model represents a prototype on which an operational Decision Support System could be based to assist forest managers over the short-medium term.
