Ecological niche suitability model with an application in Taojiang land use planning

Ecological suitability analysis is an important step in ecological planning. It applies the basis toestablish a sound development planning. In this paper, by applying multi-dimension niche concept, an eco-logical niche suitability (ENS) model was developed. The ENS model, combined with geographical informa-tion system (GIS) and spatial simulation, was used to analyze regional resources and environmental features ,and identify the suitability of regional resource and environment to regional development. An application ofthe ENS model in Taojiang agricultural land use planning is presented.

SUSTAINABLE LAND USE PLANNING BASED ON ECOLOGICAL HEALTH——Case Study of Beiwenquan Town, Chongqing, China

This paper, taking Beiwenquan Town of Beibei, Chongqing as an example, assessed the impacts of land use on ecological health by comprehensive index method, and discussed methodological system of sustainable land use planning based on ecological health. Results indicated that: 1) From 1992 to 2002, land use changes focused on 12 patterns with the total conversion area of 92.11%, which were related to cultivated land, residential and industrial-mining area, and orchard land. Urbanization and economic reconstruction were the leading driving forces. 2) There was obvious difference of the areas of ecotypes driven by land use change in wide valley and mild slope between 1992 and 2002, while there were little or no difference in steep slope and very steep slope. 3) Both of the conditions of ecological health in 1992 and 2002 were sound, and the ecotypes focused on the types of health and sub-health. But, health ecosystem in 1992, with an area of 764.64ha, accounting for 38.51% of the total evaluation area, was better than that in 2002, with an area of 636.10ha, accounting for 34.19% of the total evaluation area. 4) The ecotypes involved into different ranges have already degenerated, due to humankind’s disturbance, while the conditions of ecological health in the same ranges in 1992, regardless of stability and reconstruction, were better than that in 2002. 5) The planning scenario based on ecological health was accorded with the practice condition of Beiwenquan Town: 388.29ha of cultivated land could meet the Beiwenquan demand of food and byproduct; 1045.26ha of forest land area, the Beiwenquan demand of ecological health; and 1004.73ha of the residential and industrial-mining area, the Beiwenquan building demand. 6) Sustainable land use planning based on ecological health had higher useful value, because it not only stood to ecological theory, but also satisfied the developmental demand of society and economy.

Ecological planning of land use in the central area of Tianjin,China

This paper is attempted to develop a set of suitable principles and methodologies for urban ecological planning of land use,to analyze the ecological suitability of different kinds of land use patterns of Tianjin City, to help local decision makers to work out concrete ecological strategies for promoting a sound development of the city and for improving the life quality of the citizens, and to provide the decision makers with a new approach for solving the environmental problems brought about by the improper mixture of industry and residence.

Study on the Programming Standard for Ecological Rescue in General Land Use Planning

This paper aims at establishing the operation idea based on the analysis of the connotation,principles and reference indexes for programming standard for ecological rescue.The paper puts forward that the programming standard should take into account the natural,social and economic reference indexes,and modifies the scale and distribution of the ecological rescue according to the order of ecological safety,social safety and economic development.The paper suggests that the land planning department should strengthen the study and datum accumulation in order to establish the technology regulations of programming standard of the ecological rescue.

MSPA-based Collaborative Evaluation and Planning Governance of Territory and Natural Environment in Metropolitan Agglomerations-A Case Study of EGIDDZ in Yangtze River Delta

The intersection of environmental conservation and urban development has garnered global attention.This study aims to contribute to the theoretical foundation and policy recommendations for the collaborative governance of territory and the natural environment in metropolitan agglomerations.Employing a comprehensive Morphological Spatial Pattern Analysis(MSPA)approach,this research analyses and overlays various indicators,constructing an integrated evaluation system based on“natural resource management and conservation,land use,and ecological network assessment”.Our findings reveal that:(1)The overall collaborative degree between the spatial configuration and natural environment in the Ecological Green Integration Development Demonstration Zone(EGIDDZ)is relatively high and still needs improvement at the micro level.Notably,regions characterised by elevated synergy levels exhibit considerable spatial overlap with ecological green cores outlined in territorial planning.(2)The selection and distribution of land use patterns are pivotal factors influencing collaborative levels,with multiple land use types favouring enhanced collaboration.By exploring the interplay between metropolitan territory and the natural environment using MSPA,this study seeks to provide holistic evaluation methodologies and governance insights for advancing sustainable urban planning and development.

美国土地休耕保护计划及借鉴

美国土地休耕保护计划工程由美国政府投资,美国农业部负责实施,农民自愿参与,以期获得长期生态环境效益。CRP工程实施20多年来,美国的水土流失明显减少,土壤质量显著提高,环境质量大为改善。在美国土地休耕保护计划的执行过程中,其生态补偿的实施因其独特的理念和方式也取得了较大的成功,值得我国借鉴。

经济与生态效益不同情景下的广州市土地利用优化配置

缓解生态保护与经济发展之间的矛盾已成为广州市目前亟须解决的重要现实问题。通过对经济效益和生态效益最大化的不同侧重,基于多目标规划模型与CLUE-S模型对广州市2025年不同情景下的土地利用进行优化配置。结果表明:(1)与现状相比,兼顾两者效益情景的土地利用优化方案最为合理:效益提升最为协调分别为9.35%、9.58%,不同景观类型破碎化程度适中;(2)广州市对生态、经济效益的不同侧重主要导致林地、建设用地和水域面积的变化较大,未来规划应注重这三种地类的合理规划;(3)多目标规划与CLUE-S模型的结合,可以有效解决广州市多情景的土地资源优化配置模拟。研究结果对广州市土地利用可持续发展和生态文明建设具有较大的参考价值。

规划管制下农田生态补偿的研究进展分析

基于特殊的土地基本国情,我国实施严厉的管制制度及措施强化对优质农田的保护及管理。然而,采取禁止性或限制性强的规划管制制度,严格限制或剥夺管制区域内相关群体使用资源和空间的权利,如未提供相应的补偿或经济援助,将侵害建设区和保护区内群体的发展机会及利益,导致不同分区利益群体福利非均衡,违背环境公平。论文从农田保护的政策绩效评价、发展受限制地区实施农田生态补偿制度的机理、农田外部效益及补偿标准的测度、农田管制损失补偿及外部效益产权界定、农田生态补偿制度实施绩效及福利效应研究等方面梳理总结了国内外关于规划管制下农田生态补偿的相关研究进展及发展动态,并提出在国家实施生态补偿机制及推进主体功能区划形成与落实等政策契机下,制定基于主体功能区划框架下的农田生态补偿机制及政策,有重要的理论及实践意义。
