Land use changes in the environs of Moscow

This paper focuses on several aspects of land use change in Russia during the 1990s with a particular focus on the environs of Moscow. These aspects include modes of farming, recreation, ownership of land, and concentric zones of outwardly declining land use intensity that resemble Von Thunen's economic landscape. These zones are given special attention. In contrast to other land use aspects, the analysis of which indeed reveals a fair amount of change bringing the environs of Russian cities one step closer to their Western counterparts, concentric agricultural land use patterns with outwardly declining productivity suggest continuity rather than change.     

基于灰色线性规划的土地利用结构优化——以云南省澜沧县为例

土地利用结构优化是编制土地利用总体规划的基础和核心。以云南省澜沧县为例,分析该县2000年土地利用结构和社会经济结构状况,以最优化理论为指导思想,运用灰色线性规划方法,结合其未来社会经济发展的需求和有关控制指标,优化该县2015年土地利用结构,为全县土地资源的合理开发利用,获取最佳的社会、经济和生态效益提供“定量”的参考,最终促进区域社会经济又好又快发展。     

基于知识的旱地生理趋势的评价模型

The present study aims the evaluation of bio-physical characteristics towards soil-water-vegetation stress and a rule is envisaged to assess the degree of temporal changes. The digital rule for assessment is initialized through the index of land Instability (ILI) where the variance indicates the temporal instability of the pixel I.e., smallest land unit. It is assumed that the biophysical characteristic of land is in command of land-dynamics where there is no change in Land Use/Land Cover (LU&LC). The intensity map on tendency of albedo (IALB) assesses the intensity of soil erosion and water stress whereas intensity map on tendency of NDVI (INDVI) appraises the stress on vegetation. The carry-out study covers a part of semiarid Western India. Primarily remote sensing technique, which carries the digital information of land temporally and spatially, is adopted in this paper. A part of the study area is represented using two sets of IRS 1A/lB LISS-I data of March with a decadal time domain (1989-1998) as a test area. It is assumed that the soil-water-vegetation stress is maximum during summer(March-April-May) in any tropical belt and decadal data will stretch the possibility of climate as well as man-made activity over the land.     

Book Review

In this paper, we examine the applicability of spatial optimization as a generative modelling technique for sustainable land‐use allocation. Specifically, we test whether spatial optimization can be used to generate a number of compromise spatial alternatives that are both feasible and different from each other. We present a new spatial multiobjective optimization model, which encourages efficient utilization of urban space through infill development, compatibility of adjacent land uses, and defensible redevelopment. The model uses a density‐based design constraint developed by the authors. The constraint imposes a predefined level of consistent neighbourhood development to promote contiguity and compactness of urban areas. First, the model is tested on a hypothetical example. Further, we demonstrate a real‐world application of the model to land‐use planning in Chelan, a small environmental amenity town in the north‐central region of the State of Washington, USA. The results indicate that spatial optimization is a promising method for generating land‐use alternatives for further consideration in spatial decision‐making.     

基于批判地缘政治学视角解读经典地缘政治理论

大国间的争霸与兴衰更替,无不受地缘法则的支配。地理学者应紧跟时代的步伐,准确把握国家利益之所在,抓住机遇为民族伟大复兴做出贡献。但是,缺乏对地缘政治学的历史和哲学的批判将不能准确理解和有效实践地缘政治理论。本文简要介绍了批判地缘政治学的发展,总结了批判地缘政治学的3个特点,据此对4个经典地缘政治理论进行了解读。为了简化解读过程,首先提出了一个解读4个经典地缘政治理论的分析框架;其次根据这个分析框架重点解读了麦金德的"历史的地理枢纽";最后对4个经典地缘政治理论进行了批判性总结。通过批判性解读,得出经典地缘政治理论既有科学性一面,也有假说性和理念性的一面。经典地缘政治理论构建是基于国际地缘格局、国家利益空间分布、国家间空间冲突而构建的,并展现了理论建构者的身份,体现了地缘政治理论的历史性、社会性、情境性和地理知识—权力结构。     

莒县土地整治和占补平衡工作的探讨

通过对低效利用、不合理利用、未利用土地进行田、水、路、林、村整治挖潜,切实提高土地利用效率;通过农村建设用地挖潜利用规划,出台了专门的规范性文件,建立了专门的土地整治资金筹措机制;充分尊重群众意见,对安置区新房建设实行因地制宜、统一配套等手段,使土地综合整治在基层扎扎实实开展起来,有效地服务了新农村建设,增加了建设用地指标,保障地方经济社会发展,保护了有限的耕地资源,统筹了城乡土地配置,确保了全县耕地总量动态平衡。

珠江口盆地沉降史定量模拟和分析

运用Petrosys盆地模拟系统，定量和动态地模拟了珠江口盆地三个主要坳陷的沉降过程，论述了沉降速率的变化与生储盖发育之间的关联，认为珠江口盆地构造沉降史具有幕式、多阶段变化的特征。盆地第一幕和第二幕沉降是盆地发育的主要时期，奠定了盆地的构造格架，形成了盆地主要的沉积地层和油气资源。第三幕沉降为盆地的改造和完成阶段，是盆地区域盖层发育的主要时期。
