在当今世界土地资源极度紧缺的大背景下,研究不同土地利用情景下的生物多样性,评估其达到生物多样性预期目标的能力,已成为土地规划领域的重要研究方向,具有重要的理论研究意义和实践价值。本文在大量文献研究的基础上,简要分析了土地利用对生物多样性的作用机理,详细总结了土地类型组成、土地利用连接度、土地利用强度与土地利用聚合度4个关键性因子对生物多样性绩效影响的研究现状。针对现有研究进展,从多样性指标、生态机制、时空异质性、参与情景模拟、非线性系统规律5个方面阐述了如何进一步完善土地利用与生物多样性的研究内容。研究结果表明,土地利用与生物多样性绩效的关系符合复杂适应性系统在风景园林规划中运用的规律,满足构建研究规划协同实践的概念性框架。进而重点从引导以生物多样性保护为重要目标的用地控制策略、建立多尺度一体化的生物多样性保护格局、发挥不同尺度蓝—绿网络体系的载体作用、构建区域层面的生物多样性发展骨架、提高城市环境下生物多样性的引导措施、推进不确定性规划减少决策风险6个方面提出了土地利用—生物多样性绩效关联分析对风景园林规划中可资借鉴的思考。 相似文献

Taking the Yellow River Delta for example, this paper applied remote sensing and GIS to explore land use changes in the local area from 1980 to 2010. The results showed that arable land, and urban and rural construction land were major land use types in the Yellow River Delta, unused land also took a large ratio; land use changes occurred mainly in coastal regions, in terms of change matrix, 25.46% of the grassland was reclaimed as arable land, unused land also witnessed great changes, specifi cally, 11.14% turned to arable land, 23.25% to construction land. This study provided references for the land use planning and development of the local area. 相似文献

气候变化引起的海平面上升以及人口快速增长引起的土地利用变化为新时期全球沿海低洼地区的土地利用规划带来了新的挑战。有别于传统的土地利用规划理念与方法,引入韧性城市的概念,以美国佛罗里达州马坦萨斯河入海口地区应对气候变化和人口快速增长的韧性土地利用规划为例,通过构建基于地理信息系统的综合模型,整合海平面上升影响模型、物种栖息地模型和土地利用预测模型来预测适应海平面上升的土地利用规划方案。研究的结果可为中国沿海地区特别是三角洲地区应对气候变化提供借鉴。 相似文献

基于“三生”功能的柳州市国土空间适宜性评价 总被引:1,自引:0,他引:1
国土空间适宜性评价是空间规划的前提和基础。文章以国土资源现状为本底,从土地资源、水资源、生态、环境、气候、灾害和区位等资源环境要素角度构建评价指标体系,从资源本底和土地利用现状两方面分别对柳州市开展生态保护、农业生产及城镇建设适宜性评价,并将生态、农业和城镇综合评价结果在空间上进行叠加分析,逐块分析每个网格单元需要的生态保护、利于农业生产与适宜城镇开发建设的功能等级,确定各图斑单元的功能属性,划分形成以生态保护、农业发展和城镇开发为主导功能的三类国土空间格局。 相似文献

Interaction between farming systems, riparian zones, and landscape patterns: a case study in western France 总被引:2,自引:0,他引:2
We analyze the factors driving land use within and outside riparian zones in four small (about 800 ha) watersheds in Brittany. The results show a difference between riparian and non-riparian zones (less used for grassland), but other factors are also important, such as field size or farm management type. In large farms, small fields are easily abandoned. A multivariate analysis with farm and field characteristics explains 30% of land use variation. Our results suggest that farm type deflects land use from the regional mode, so it is important, in the implementation of environmental zoning, to assess constraints at the farm level. 相似文献

Local land use controls have received considerable attention from political economists, but statewide land use controls have not. This research note offers an analysis of the political economy of statewide land use controls in Oregon. Unlike two previous studies, which indicate that such controls generally serve the upper class, this research note asserts that the statewide land use program in Oregon subsumes four identifiable issues, which generate the necessary supporting coalition among distinct groups. These results suggest that the political viability of statewide land use programs depends critically on public perception of how they address the issues that affect the voters. 相似文献

Based on the TM remote sensing interpretation of land use data of a non-point source pol uted area in southern China in 2015, supported by ArcGIS and the fractal theory, this paper established the perimeter-area fractal equation of the spatial structure of land use types, quantitatively calculated the fractal dimension and stability index of various land use types in this non-point source polluted area in 2015, and analyzed the spatial structure characteristics of land use types. The results showed that the fractal dimension values of the different land use types in the research area ranged 1.141–1.657, and the whole fractal dimension of the research area was 1.206. To be specific, the fractal dimension values of unused land, grass land and rural residential land were high, and the fractal dimension values of dry land, paddy filed and waters were low, and the fractal dimension values of urban land, industrial traffic construction land and forest land were moderate. The area of the land use types whose stability index values were 0.2–0.4 accounted for 89.5% of total area, suggesting that the stability of the spatial structure of land use types of Beibei District in 2015 was not high generally. The rural residential land and urban land of the research area should be planned and managed more properly from now on. 相似文献
