基于PSR模型的佳木斯市土地生态安全综合评价   总被引:7,自引:0,他引:7  
研究基于PSR模型框架,从压力、状态、响应等3个准则层入手构建佳木斯土地生态安全的评价指标体系,结合熵权与变异系数的综合确权法测算各指标权重,对佳木斯市2000~2012年土地资源生态安全进行综合评价,划定其安全等级。研究表明:2000~2012年,佳木斯市的土地生态安全系统的压力指数整体低于状态指数与响应指数,呈先上升后下降再上升的波动形变化趋势,压力指数从0.084上升到0.129,下降到0.041,再上升到0.157;土地生态安全状态指数呈现先增长又下降的变化趋势,从0.158增长到0.251,再下降到0.208;土地安全状态响应指数呈现平缓的增长变化趋势,从0.140增长到0.308;压力指数、状态指数和响应指数共同决定佳木斯市土地生态安全评价的综合指数,土地生态安全指数呈现先增长后下降再增长的变化趋势,从0.381增长到0.494,下降到0.464,再增长到0.673。考察期内佳木斯土地生态安全整体处于临界安全状态,2012年上升至较安全等级。该结论为佳木斯市制定改善土地生态安全的措施提供理论依据。  相似文献

城市公园是城市的重要组成部分,是调节城市生态环境的重要场所,也是城市居民休憩、娱乐和活动的重要开敞空间,因此分析城市公园设施的利用情况以及利用者的行为特性,对于城市公园的建设和管理有十分重要的意义。以上海市中山公园为例,通过对该公园利用情况的分析,了解到公园的利用者大多数为青年人和老年人,且利用者范围广,利用频率高,滞留时间也较长。同时运用数量化Ⅲ类和聚类分析方法,把城市公园利用者的行为特性分为郊游式利用型、日常利用型、临时利用型、约会利用型、幼儿同行利用型、健康注重型及非日常团体活动型7大类,分析了各类利用者行为特性的特点,为今后政府部门对公园的建设和管理提供一些新的思路。  相似文献

进行城市土地集约利用评价对加强城市土地集约利用与管理具有重要意义,结合广东省惠州市城市发展现状,从土地投入强度、土地使用强度、土地使用效益和土地生态环境4个方面选取12项指标构建惠州市城市土地集约利用综合评价指标体系,采用熵权—模糊综合评价模型对惠州市2009—2013年城市土地集约利用情况进行综合评价,研究结果表明:(1)2009—2013年惠州市城市土地集约利用水平呈现先下降再上升的波动状态,2012年的水平为近5年最低值;(2)2013年惠州市城市土地集约利用水平虽有所改善,但从整体看,研究时段内集约利用水平都处在"较低~中等"等级。惠州市应该努力转变城市土地管理和利用方式,积极探索"低投入,高产出"的土地集约利用模式,大力发展循环经济,逐步实现城市土地配置科学化、布局合理化、使用高效化,进一步提高城市土地集约利用水平。  相似文献

In a globalized urban world, cross‐border metropolises represent a spatial configuration emblematic of the interplay between the space of flows and the space of places. The multiplicity of contexts and processes at work can complicate the identification of what constitutes the singularity of the concept. In order to contribute to these reflections the present article hypothesizes that the specificity of cross‐border metropolises does not fundamentally stem from the form they take or the nature of the cross‐border integration at work, but rather from the particular role played by national borders in their formation. Opening up borders offers new opportunities for border cities and urban border regions to reinforce their positions at the heart of global economic networks, and to affirm their autonomy as cross‐border regional entities. Without minimizing the possible obstructive effects of borders, it is helpful to recognize that they might also represent a resource in the composition of cross‐border metropolitan regions.  相似文献

我国农民收入来源主要包括农业经营性收入、务工收入及其他收入。城镇化发展是农民增收的重要动力之一,十八大以来新型城镇化被提到一个新高度。新型城镇化要求把生态文明理念融入城镇化过程,实现集约、智能、绿色、低碳的发展目标。新型城镇化条件下,农民增收能否持续、高速的发展成为新的课题。文章对湖北省部分市(县)采取实地查勘、问卷调查与走访农户、搜集资料、逻辑分析的方法就湖北省新型城镇化条件下农民增收进行研究。研究结果表明:(1)新型城镇化促进农业现代化发展,提高农产品产值,减少农业产业链内耗,实现农民增收;(2)新型城镇构建农民市民化社会构架,提高了农民工资收入与社会福利收入,增加了农民收入;(3)新型城镇化改变发展模式,增加农民资产性收入与提升了农民生活品质,实现更高水平的增收。研究结论:新型城镇化是未来农民增收最主要的推动力。  相似文献

The proliferation of religious spaces is a relatively recent development in Nigeria. Nowadays there are more than a hundred religious camps belonging to different religious groups in the country. The most popular of these camps, the Redemption Camp of the Redeemed Christian Church of God, is located 42 kilometres outside of Lagos and measures several thousand acres. Although initially not designed as such, developments in and around Lagos have compelled the managers of the Redemption Camp to present it as an urban alternative to the city of Lagos, which is generally deemed chaotic. The prestige of this camp and its activities have led to expansive urban development that involves the creation of numerous residential estates stretching from Lagos to beyond the Redemption Camp. Based on a recent ethnographic study of the Redemption Camp, this article argues that the process of urban expansion in and around Lagos is propelled by an aggressive form of religious revival that transcends the borders between economics, spirituality and territorial conquest. This article thus illustrates how church‐driven, religio‐urban developments follow a different logic of city making than often presumed by theorists of African cities, who generally neglect the religious forces that inform urban transformations in Africa.  相似文献

This article analyses the development and marketing of Islamic gated communities in Basaksehir, Istanbul. It demonstrates how a blueprint of public–private urban development was appropriated by middle‐class Islamists. The gated communities in Basaksehirwhich, at the outset, were not explicitly religious—gradually became attractive to religious actors searching for enclosed urban enclaves where Islamic communities would be protected against perceived moral‐urban threats. While urban‐religious enclaves appear to bear similarities to pre‐modern Ottoman Islamic urban enclaves, the rise of contemporary Islamic gated communities should be understood in light of the recent coming to power of the Islamist Turkish government. In cooperation with this government, housing development agencies approached Islamic investors to find capital for their public–private housing projects. One of the results of this form of urban development is that, contrary to pre‐modern Ottoman Islamic urban enclaves, the Islamic gated communities are homogenous in terms of economic class, catering specifically to the Islamic middle classes. Moreover, people who invest in Basaksehir desire an urban‐religious lifestyle that differs from the ‘traditional' religious lifestyle experienced in ‘traditional' Islamic neighbourhoods. The specific urban‐religious configuration generates a new type of Islam that better fits middle‐class values and a middle‐class lifestyle.  相似文献

The introduction to this symposium on entrepreneurial religion and neoliberal urbanism discusses leading scholarly approaches to religion and urban theory, arguing that, despite their merits, these approaches are in need of refinement. Theories on religion and urban theory too often describe religion as a reactionary phenomenon. Religious movements and spaces are generally defined as pockets of resistance and shelter against retreating or failing states under neoliberal restructuring programmes in the shadow of consumption dreams. Although religious actors and ideologies unquestionably form part of urban groups that are denied access to public and private means to wealth and security, the contributors to this symposium argue that within a global, comparative perspective, the entwinement of religion, state and market reveal more complicated configurations. Through a comparison of Islamic gated communities in Istanbul, Pentecostal prayer camps in Lagos and Pentecostal grassroots movements in the favelas of Rio de Janeiro, this symposium demonstrates that urban religion should also be regarded as a constitutive force of contemporary capitalism and should therefore be placed at the heart of the neoliberal construction of urban space instead of at its margins.  相似文献

This article scrutinizes the much used, but less examined, concept of ‘trickle down' in an urban setting. We make a distinction between the production of and distribution in the city, and argue that trickle down in contemporary urban policy could be regarded as the liberal link between production and distribution. Based on interviews with key figures and document analyses, we look at the transformation of the Swedish city of Malmö from an industrial to a post‐industrial city, where, during the last two decades, we have found three concurrent components: the ideology of trickle down; several urban policy programs and governmental policies to ‘make' money and resources trickle down; as well as increased economic polarization and segregation. A liberal critique of trickle down would argue that market mechanisms cannot by themselves solve distribution, and that government policies therefore are needed. We argue for the need to go beyond a liberal critique of trickle down and stress how unequal distribution is built into the unequal production of the city.  相似文献
