非典型历史街区遗产保护的社区参与策略研究——以重庆水土老街陵江社区为例

历史文化街区的遗产价值已得到普遍认同,并通过“精英式”“重投入”的方式被率先保护。而相较于历史文化街区,非典型历史街区面临社会关注度低、企业和政府投入不足、社区参与程度低下等一系列保护困境。基于此,建构了社区参与内生性因素和外源性因素相结合的遗产保护策略。以重庆市北碚区水土老街陵江社区为实证案例进行深度剖析,提出内生性因素“需求匹配”“能力输出”“价值认同”刺激居民自发参与,外源性因素“赋利”“赋能”“赋智”引导居民主动参与。进一步总结为“激励”“实施”“保障”层面的社区参与策略,以期为此类型历史街区的遗产保护提供思路借鉴。

2018—2022年重庆市巴南区农村饮用水监测结果分析

目的分析2018—2022年重庆市巴南区农村生活饮用水的卫生情况,了解该地区饮用水水质的变化趋势,并为水质管理和规划改善提供理论依据。方法收集整理2018—2022年巴南区农村生活饮用水的监测信息,根据《生活饮用水卫生标准》(GB 5749-2006)判断其达标情况。采用卡方检验或Fisher精确检验分析重庆市巴南区农村饮用水在不同年份、水期、水样、水源类型以及消毒方式下的达标率差异。结果2018—2022年,重庆市巴南区共监测农村饮用水460份,达标率为81.30%。5年内水样达标率存在差异(χ^(2)=13.05,P=0.011),但没有明显的上升趋势(P趋势=0.083)。不同水期和水样类型下的达标率差异均无统计学差异(P>0.05)。不同水源类型(χ^(2)=16.89,P<0.001)、不同消毒方式(χ^(2)=12.22,P=0.002)的水样达标率存在明显差异。在丰水期,江河水源的生活饮用水达标率(96.88%)普遍高于来自水库(85.06%)和其他类型水源(包括沟塘和深井水)(54.17%)的水样达标率(χ^(2)=14.52,P<0.001)。在枯水期使用液氯和次氯酸钠消毒的生活饮用水明显高于二氧化氯消毒的水源(χ^(2)=14.03,P<0.001)。同一水源中,使用复合二氧化氯消毒的达标率在枯水期(90.63%)高于丰水期(81.25%)(χ^(2)=4.66,P=0.031)。在所有检验指标中,微生物指标的合格率较低,为83.26%。结论2018—2022年重庆市巴南区农村饮用水的卫生安全有待提高,其中微生物指标是其主要影响因素。该地区应加强对农村饮用水从“源头”到“水龙头”的监管和保护,从根本上提高饮用水质量,以保障居民的健康。

集体经营性建设用地入市农户满意度影响因素研究——基于Logistic-ISM模型的分析

农户满意程度可以反映政策改革成效,探究农户集体经营性建设用地入市满意度影响因素,有助于评价政策实施效果,同时对提升农村发展和农民幸福感也有一定的现实意义.采用问卷调查和访谈的方式,选取重庆市大足区作为研究区域,基于Logistic模型确定农户满意度的影响因素,结合ISM模型分析各影响因素之间的层次关系,对农民的政策实施满意度影响因素进行实证分析.研究结果显示:(1)针对入市实施效果,绝大部分农户持满意态度,不满意的地方集中在收益分配不及时和环境污染方面;(2)家中是否有村干部、生态环境变化情况、是否参与表决、分配公平性、入市实际收益、程序透明性、入市风险存在情况、对入市土地所有者的认知对入市农户满意度有显著影响.其中对入市土地所有者的认知、入市风险存在情况、入市实际收益为表层直接因素,中层间接因素有生态环境变化情况、是否参与表决、分配公平性以及程序透明性,家中是否有村干部为深层根源因素.应进一步完善土地产权制度,明晰入市到期后土地权属问题;健全监督管理机制,建立集体经营性建设用地入市单位的产业目录和准入标准制度;完善收益分配机制,制定集体土地入市指导性分配意见;将村集体负责人纳入政府基层领导队伍体系,提高程序透明性.

城市空间水体热环境效应研究——以重庆市主城七区为例

水体作为地表热环境的重要敏感因子,对缓解热环境效应具有重要作用。基于2003、2011和2019年土地覆被数据与热环境指数数据,以重庆市主城七区为例,将景观格局与热环境相结合,利用空间分析和相关性分析探究地表重要覆被对水体降温能力的影响以及水体对热环境效应的具体调控机制。结果表明:①水体相比裸地、植被、建成区覆被类型,其热环境指数处于最低水平,与热环境效应呈显著的负相关性,有良好的降温效果,且单位水体比单位植被降温作用更强;②水体与植被之间存在相互作用,且随着植被比例增加,水体的降温效果越差;在非城市用地中,植被的降温效果最好,随着城市发展密度的增加,水体的降温效果也逐渐增强,超越植被调节热环境的能力;③水体自身热环境与水体形状指数无关,与面积、长度、宽度、深度因素有关,且在一定范围内,随着面积、长度、宽度和深度的增加,降温效果有所提升;④随着缓冲距离的增大,水体的降温效果逐渐下降,河流的最佳降温范围为200 m左右,水塘和水库的有效降温范围在300 m左右。为促进城市热环境的改善,未来应因地制宜利用城市空间增加绿化、加强水体循环等机制来缓解城市热环境效应,实现城市生态的稳定和可持续发展。

城市生态公园生态—文化耦合评价及优化策略研究——以重庆市渝北区为例

城市生态公园在重庆城市绿地系统中扮演重要角色,既提供自然生态功能,也满足市民休闲娱乐需求。然而,目前其生态和文化效益未得到充分发挥。本研究采用样方法、访谈法和观察记录法,对渝北区城市生态公园进行调研,构建了生态-文化功能耦合评价体系,揭示了重庆城市生态公园的特征和建设问题。研究发现,这些公园具有多样的生境类型和良好的绿色生态本底,但在生境营造、植物多样性、游憩空间、服务设施、科普宣教和可达性方面存在不足。针对这些问题,研究提出了优化设计思考,包括公园边界、植物配置、游憩空间、科普宣教和可达性改善。这些成果为提升重庆城市生态公园的品质和规划设计提供了依据和指导。

基于多源数据的山地县域绿色基础设施网络构建及修复策略——以重庆市万州区为例

以重庆市万州区为研究区,以生物多样性为切入点,综合运用形态学空间格局分析(MSPA)和最小累积阻力模型(MCR),识别GI网络中心(hubs)和连接廊道(links),结合图论、电路理论及几何形态学划分重要性等级,提取廊道上的生态夹点区域,并针对山地城镇的典型生态问题提出对应的精细化保护与修复策略。结果表明:1)万州区内网络中心42处,总面积996.35 km^(2),占研究区总面积的28.83%,总体“东密西疏”,形成“一屏三带、散点分布”的格局;2)连接廊道80条,总长度292.97 km,呈现“东强西弱、东短西长”的分布特征;3)生态夹点142处,占廊道长度的9.60%,主要分布于东部。据此,将网络中心分为连绵涵养区、重点保护区和独立修复区制定分区修复策略;将连接廊道分为关键廊道、重要廊道和一般廊道制定分级修复策略;对不同用地类型组合方式的生态夹点区域制定精准修复策略。

重庆传统风貌区街巷空间品质测度研究

随着城市更新进程的推进,重庆传统风貌区逐渐经历了不同程度的改造,然而当下更新现状缺乏量化评价和精细管控。街巷作为传统风貌区最主要的公共空间,是衡量空间品质的重要切入点。选取重庆传统风貌区共149个样点,采用街道空间品质测度方法,基于街景图像量化空间客观特征和主观感知评价,并将两者进行统计学分析。结果发现,重庆传统风貌区的围合感营造较好;更新改造可以大幅度提升通透性、整洁协调度和意象化。得到显著影响主观感知评价的空间客观因素有:界面密度、宽高比、绿视率、天空开阔度、围合度、传统风貌建筑、原生树木、文物及历史建筑、色彩饱和度、色彩明度、业态数量以及改造强度。研究旨在通过空间客观特征的优化来提升主观感知,从而实现街巷空间品质的优化。

2009—2022年重庆市万州区空气质量变化趋势研究

了解重庆市万州区空气质量的变化,对于三峡库区区域生态环境保护有积极意义。通过对重庆市万州区2009—2022年PM10、SO2、NO2浓度及2017—2022年PM2.5、O3、CO浓度的实测资料进行MannKendall非参数检验,分析了长时间序列空气质量变化特征。结果表明:PM10、PM2.5、SO2、CO浓度呈显著下降趋势,O3、NO2浓度变化趋势不显著;[NO2]/[SO2]比呈显著上升趋势,大气氧化性增强,表明应强化NO2、臭氧前体物的防控。PM2.5是空气污染主要因子,以冬秋季为甚;次之为O3,以夏春季影响明显。
