Imagineering Uneven Geographical Development in Central Florida

In an era when it is proclaimed that, through globalization, the world has become flat, the unevenness of economic and social development is often overlooked or suppressed. This case study explores the conditions of uneven geographical development in the urban space of central Florida. Focusing primarily on the Reedy Creek Improvement District (RCID), better known to much of the world as Walt Disney World, and on Celebration, the community developed by the Disney Corporation in the 1990s, the relationship between tourism, the defining economic sector in the region, and uneven geographical development is explored. This study shows that the theory of uneven geographical development applies well to a region that is heavily dependent upon the tourist sector for its economy, and thereby works to control the narrative of that space to continue attracting consumers.     

中国土地发展权的经济分析与配置设计--以北京市平谷区为例

采用综合分析法从土地规划干预的视角对土地发展权进行了经济分析,在此基础上以北京市平谷区为例进行土地发展权的定量配置设计,研究结果表明：（1）在政府有效干预下,土地用途转换所带来在农业用途基础上的价值增值即为土地发展权价值;（2）平谷区土地发展权初始配置为每公顷非基本农田土地发展权数量为0．35个,每公顷基本农田土地发展权数量则为1个,二者均有10％属于国家所有;（3）政府对土地利用干预是土地发展权存在的前提,显现了土地发展权的价值,土地发展权制度的设立又是政府干预的补充;（4）土地发展权在土地所有者和国家之间分配,国家的份额比例相对较小。     

Relict rock glaciers in Wasdale, western Lake District, northwest England: geofact or geofantasy

Field examination of four landforms in the Wasdale area of the western Lake District that have previously been classified as relict rock glaciers indicates that such designation is no longer appropriate. Two of the features consist of bedrock with clusters of locally derived boulders; another is largely the product of glacial deposition with some evident fluvial modification; the fourth resembles a series of solifluction lobes, which may also have undergone some fluvial alteration. Use of these features to draw palaeoclimatic inferences concerning permafrost and temperature is no longer tenable.

农村公共服务设施空间布局优化研究——以北京市顺义区为例

合理布局农村公共服务设施是改善农民生产和生活环境的重要手段之一,也是农村土地综合整治和新农村规划中的重要组成部分。以北京市顺义区为例,首先结合《土地利用现状分类》对公共服务设施的归并特征和实地调查,对顺义区公共服务设施进行级别划分;其次对农村居民点发展实力与乡镇和区(县)级别公共服务设施的通达性进行分析,并确定未来农村居民点发展模式,作为农村公共服务设施空间布局优化的空间依据;最后,以农村医卫慈善用地为例进行公共服务设施空间布局优化的方法探讨,研究成果可为编制城乡统筹和区域均衡发展的土地利用总体规划与土地综合整治规划提供参考。

Meteorological drought analysis using data-driven models for the Lakes District,Turkey

Abstract

Droughts may be classified as meteorological, hydrological or agricultural. When meteorological drought appears in a region, agricultural and hydrological droughts follow. In this study, the standardized precipitation index (SPI) was applied for meteorological drought analysis at nine stations located around the Lakes District, Turkey. Analyses were performed on 3-, 6-, 9- and 12-month-long data sets. The SPI drought classifications were modelled by Adaptive Neural-Based Fuzzy Inference System (ANFIS) and Fuzzy Logic, which has the advantage that, in contrast to most of the time series modelling techniques, it does not require the model structure to be known a priori. Comparison of the observed values and the modelling results shows a better agreement with SPI-12 and ANFIS models than with fuzzy logic models.     

Long-term variations in orographic rainfall: analysis and implications for upland catchments

Abstract

Climatic changes could alter the frequency and magnitude of rainfall events and the distribution of rainfall with altitude, with important consequences for management of aquatic ecosystems, water resources and flood risk. This study investigates changes in observed rainfall amounts across a range of altitudes in the Lake District region, northwest England, and spatial and temporal changes to the orographic “rainshadow” effect. Between the 1970s and 1990s there have been marked changes to the seasonality of precipitation, such that winters have become wetter, and increasingly dominated by heavy precipitation events. The intensity of these events has increased most markedly at higherelevation sites. Such changes could hinder recovery of sensitive upland sites from acidification and increase the risk of downstream flooding. An inter-decadal weakening of the region's rainshadow suggests a greater proportion of winter precipitation crosses the high-elevation Lake District dome. This is linked to changes in the frequency and character of wet weather patterns.
