针对广东湛江湾海底隧道施工中出现的盾构废弃泥浆脱水速率慢、泥渣含水率高与废浆排放污染等问题，研发了一种新型H型脱水试剂。通过絮凝脱水试验、微观机理试验以及现场生产试验，揭示了泥浆泥水分离体积比/上清液浊度/粒径分布和Zeta电位等变化规律，综合评价H型试剂与3种聚丙烯酰胺（PAM）在泥浆脱水效果方面的差异。结果表明：H型试剂与泥浆作用的最优添加量为0.5%；与PAM相比，H型试剂前期沉降速度较慢，但脱水后的泥渣含水率降低了约18.1%，且上清液非常清澈，7.8的pH值符合直接外排条件；H型试剂兼具了较好的桥网作用与电中和作用，使粒径<10μm的细粒更容易聚集成50μm以上的大颗粒，加快了泥浆的絮凝速度。H型试剂营造了渗水性更强的Ca排水通道，降低泥浆的黏滞性，提高泥浆压滤脱水的效率；与原脱水试剂相比，现场使用0.1%的H型试剂，可提高30.5%的脱水泥样含固率，降低20%的工程成本。

针对普通线性回归分析以空间平稳数据为假设,而忽视空间数据局部变化特征的缺陷;该文以上海市西郊的青浦区为案例区,通过构建景观生态质量评价指标体系,采用综合指标评价法和等距离空间分类法,对该区184个行政村的景观生态质量进行评价和等级划分;引入局部线性地理加权回归模型用以评估压力类因素对景观生态质量的影响;对比线性回归模型、地理加权回归模型和局部线性地理加权回归3个模型在解释青浦区行政村景观生态质量空间差异的精度。结果表明：2014年青浦区各行政村的景观生态质量指数的变化幅度为0.03~5.49,呈现西部高,东部低的特征;景观生态质量与8种压力类影响因素的关系随着空间位置的改变表现出局部变化特征,即使同一因素对景观生态质量的影响在方向和大小上均表现不同;通过对比3个模型的解释结果可以判断,地理加权回归模型和局部线性地理加权回归模型在处理空间非平稳性和空间异质性上,其预测精度优于线性回归模型,而局部线性地理加权回归模型在处理由于＂边界模糊＂导致的＂边界效应＂问题上,其模拟的精度优于地理加权回归模型;村域景观生态质量变化具有空间差异性和尺度敏感性。与景观生态质量变化呈正相关的因素依次为：人均耕地面积、居民恩格尔系数和城镇化率;与景观生态质量变化呈负相关的因素依次为：人口抚养比、第二产业占GDP比例、人口密度、聚耕比、距最近城镇中心距离。研究结果可为都市郊区景观生态系统可持续发展和土地空间整治提供科学借鉴。

为探讨农户生计策略与土地利用行为之间的相互作用关系,该文以上海市青浦区为例,从人地系统角度出发,将生计策略与土地利用行为分别作为子系统构建耦合协调度模型,分析二者之间的耦合关系和耦合协调关系,并借鉴强化理论探究农户土地利用行为对生计策略的反馈机理。结果表明:1)不同类型农户在生计策略与土地利用行为的耦合关系和耦合协调关系方面存在差异:耦合关系方面,4种类型农户的耦合度集中在0.4~0.5范围内,处于拮抗阶段,其中,专业农业型农户最高,为0.480 7;耦合协调关系方面,专业农业型农户耦合协调度为0.545 9,处于高度耦合协调阶段,其余3种类型农户耦合协调度集中在0.4~0.5范围内,处于中度耦合协调阶段。2)专业农业型和农业兼业型农户的耦合协调度和土地利用效应较高,其保持原有生计策略的户数比例小于50%;非农兼业型和传统农业型农户的耦合协调度和土地利用效应较低,其保持原有生计策略的户数比例大于50%。3)专业农业型的生计策略有助于提高农户生计水平和促进耕地资源的合理利用,对从事农业生产的农户吸引力较大。研究结果可为实现农户生计与土地利用的可持续发展提供重要的理论依据。

Deeply integrated vulnerability and its evaluation framework provide a new perspective for the study of socio-ecological systems in metropolitan suburbs. A new vulnerability evaluation system of ‘exposure-sensitivityadaptability’ based on the socio-ecological system and vulnerability theory was constructed. Meanwhile, drawing on the concept of ‘spatial trap’, the concept of ‘spatial vulnerability trap’ was tried to put forward. The spatial-temporal interaction characteristics were analyzed, the existence of spatial vulnerability trap was tested and the interaction mechanism of vulnerability dynamic evolution was revealed using spatial-temporal exploration analysis method and geographic detector for socio-ecological system vulnerability of 184 administrative villages in Qingpu District from the year 1998 to 2018. The results showed that: (1) During the study period, the socio-ecological systems vulnerability of Qingpu District increased from 0.518 to 0.621, and the vulnerability level increased from low grade to medium grade. The spatial-temporal pattern showed the dynamic characteristics of first increase and then decrease and high in the East and low in the west. (2) The relative length of the socio-ecological systems vulnerability temporal path movement in Qingpu District from 1998 to 2018 showed a trend of gradual decline from the central region to the surrounding area. The mobility curvature of the vulnerability time path was relatively small, showing the spatial pattern of low in the north and high in south, and the cohesion index of the spatial transition of vulnerability is 0.496. The spatial agglomeration structure had relatively high transfer activity and low path locking. (3) No ‘spatial vulnerability absolute trap’ was detected during the study period, yet the ‘spatial vulnerability relative trap’ highlighted in the 11 administrative villages mainly distributed around the administrative boundary in the north and south of the area.
