长江经济带工业废水排放的时空格局演化及驱动因素

利用探索性空间分析方法（ESDA）和迪氏分解模型（LMDI）研究长江经济带2002~2013年工业废水排放的时空格局演化和主要驱动因素。① 时空格局演化方面,时间上工业废水排放先上升后下降,在2005年达到峰值。空间上,排放量自上游向下游增加;高排放城市减少,中排放城市增多;工业废水排放自下游向中上游转移,并由大城市向中小城市扩散;呈现明显的空间集聚状态。② 驱动因素方面,经济发展效应和技术进步效应分别是工业废水排放增多和降低的主导因素;产业结构效应的影响取决于产业发展政策的调整;人口规模效应影响较小。     

深汕特别合作区协同共治型区域治理模式研究

伴随金融风暴引发了全球资本重组,资本的空间修复客观要求以新的跨界区域治理模式组织资本与劳动力关系,而中国传统跨界产业园区建设路径依赖于区域发展中“省-地方”分层设权治理模式。以珠三角地区的深汕特别合作区为例,通过深度访谈与文本分析法,发现深汕特别合作区形成的多主体共同参与、分工合作的协同共治型区域治理模式是在传统路径依赖基础上的一次制度创新。通过分析模式产生的产业经济背景、政策制度背景与现实发展概况,并解构深汕特别合作区行政组织架构、空间发展政策及利益分配机制,发现省政府的放松管制与资源注入,地方政府的优势互补、分工协同是协同共治型区域治理模式的本质特征,而这一区域治理模式的产生将会对中国区域产业政策与空间政策及政府职能转型提供新的经验与启示。     

Green growth machines? Competing discourses of urban development in Playa Vista,California

Playa Vista is a massive mixed-use development built on coastal wetlands in west Los Angeles. Its land use story illustrates how strategically constructed discourses shape contested urban spaces. Through an analysis of newspaper reporting and government documents, this paper traces how pro-Playa Vista interests changed their growth discourses rationalizing the development between 1979 and 2015. Findings suggest that pro-growth coalitions are resilient when they modify their discourses to negotiate new regulatory and political contexts, specifically pursuing sustainability fixes. They are not dogmatic in their adherence to orthodoxies of private property rights and “highest and best use” of land but rather continually reconstruct growth discourses incorporating enough of the values of their opponents (i.e. “green” values such as growth management and smart growth) that some environmental and homeowner citizens’ groups join the growth coalition, forming a “green growth machine” that not only profitably builds on the land but finances ecological restoration.     

红阳猕猴桃种植基地自动站温度对其生长季的影响

利用贵州西部发耳、米箩、猴场、蟠龙、鸡场、顺场、杨梅、勺米共8个红阳猕猴桃基地2013—2015年物候期观测资料、猴场基地红阳猕猴桃果实生长期生长速率及其产量资料以及各基地2005—2015年温度资料,运用C值逼近法和决定系数(R~2)最大化法拟合红阳猕猴桃果实生长曲线,采用相关性分析方法,分析了温度对红阳猕猴桃物候期的影响。结果表明,红阳猕猴桃各个物候期出现的时间及其日数与温度变化具有一致性,但各个物候期对温度的响应表现出不一致。红阳猕猴桃开花期对平均温度、平均最高温度的响应最为明显,其相关性达到极显著水平(p0.001)。平均最高温度对果实生长期日数的影响呈负相关性,其相关性达到极显著水平(p0.005)。果实生长量的75.69%受时间影响,24.31%受气候因素影响。     

Major neotectonic features of eastern Marmara region,Turkey: development of the Adapazarı–Karasu corridor and its tectonic significance

Eastern Marmara region consists of three different morphotectonic units: Thrace–Kocaeli Peneplain (TKP) and Çamdağ–Akçakoca Highland (ÇAH) in the north, and Armutlu–Almacık Highland in the south of the North Anatolian Fault Zone (NAFZ). The geologic‐morphologic data and seismic profiles from the Sakarya River offshore indicate that the boundary between the TKP in the west and ÇAH in the east is a previously unrecognized major NNE–SSW‐trending strike‐slip fault zone with reverse component. The fault zone is a distinct morphotectonic corridor herein named the Adapazarı–Karasu corridor (AKC) that runs along the Sakarya River Valley and extends to its submarine canyon along the southern margin of the Black Sea in the north. It formed as a transfer fault zone between the TKP and ÇAH during the Late Miocene; the former has been experiencing extensional forces and the latter compressional forces since then. East–West‐trending segments of the NAFZ cuts the NE–SW‐trending AKC and their activity has resulted in the formation of a distinct fault‐bounded morphology, which is characterized by alternating E–W highlands and lowlands in the AKC. Furthermore, this activity has resulted in the downward motion of an ancient delta and submarine canyon of the Sakarya River in the northern block of the NAFZ below sea level so that the waters of the Black Sea invaded them. The NE–SW‐trending faults in the AKC were reactivated with the development of the NAFZ in the Late Pliocene, which then caused block motions and microseismic activities throughout the AKC.

Chemical alternation of waters in the Kuroshio/Oyashio Interfrontal Zone

An intensive survey has been conducted of the distributions of some chemical properties (dissolved oxygen, nutrients and carbonate properties) in the Kuroshio/Oyashio Interfrontal Zone. Many low-salinity water patches were found down to depths of 640 m. Each chemical property also showed anomalies in these patches, but the degree of variation showed a low correlation with salinity. This may be due to the high variability of biological processes in the surface waters where these patches are formed. Vertical profiles of the chemical properties were also observed along the Kuroshio extension axis from 140.50°E to 146.75°E. The concentrations of nutrients and total carbonate (TC) in the water having densities greater than σ_θ=26.60 can be regarded as being formed by the isopycnal mixing of the Kuroshio component water and Oyashio component water and biological degradation within the density surfaces. This implies that the transport of chemical properties by the diapycnal mixing is negligible in these density layers in the K/O zone.

Stress Field Estimations for Colima Volcano, Mexico, Based on Seismic Data

 For first time, during 1991, seismic activity was recorded during an eruption at Colima volcano. We analyze these data to obtain a stress pattern using a composite focal mechanism technique. From the analysis of regional seismicity, the Tamazula Fault and the Armeria River appear as active features and the dip of the slab east of the Jalisco Block is approximately 12°. Southwest of Colima volcano a vertical alignment of seismic events was observed. We estimate five different composite focal mechanism solutions from our data set, which indicate a change of the stress field at the volcano after the 1991 eruption. These solutions suggest that the stress field in the volcanic edifice was controlled by stresses related to the emplacement of magma superimposed on the regional stress field. No evidence of active local faults in the volcanic edifice was found. We propose a model for the eruptive process that involves tilting of the volcanic edifice.
