Diagnostic Analysis on a Regional Rainstorm Weather in North-central Henan Province

[Objective] The research aimed to analyze a regional rainstorm weather process in north-central Henan Province. [Method] Based on the conventional meteorological observation data and the rainfall data of Henan Meteorological Station, the diagnostic analysis of atmospheric thermodynamics and dynamics on a rainstorm weather process in north-central Henan Province on July 19, 2010 was carried out. The characteristics of physical quantity field and the evolution of weather situation in north-central Henan Province when the rainstorm happened were studied. [Result] Western Pacific subtropical high strengthened to extend westward. The dynamic uplifting of low vortex at the middle and low layers, the strong water vapor transportation of southwest low-level jet caused the regional rainstorm weather process in north-central Henan Province. The diagnostic results of physical quantity showed that the deep, thick wet layer and the sustained water vapor convergence provided the abundant water vapor for rainstorm generation. The positive vorticity advection center developed and spread from northwest to southeast, which was favorable for the development of vertical movement. The structure maintenance of positive vorticity at the middle and low layers, negative vorticity at the middle and high levels provided the power condition for the regional rainstorm generation. The pumping effect of convergence at the middle and low layers, divergence at the high layer was favorable for the strengthening of vertical ascending motion at the low layer. The uplifting effect of dew point front at the middle and low layers triggered the release of unstable energy. The confrontation of warm and cold air was one of the important reasons for the regional rainstorm. TBB characteristic analysis showed that TBB was from -60 to -50 ℃ in north-central Henan Province in the whole strong precipitation time, and the moving speed was equivalent to that of southwest vortex. The low-value belt of TBB corresponded with the rainstorm occurrence zone in Henan, and the minimum-value center of TBB was basically consistent with the strongest center of precipitation. [Conclusion] The research provided the scientific basis for the short-term forecast of rainstorm.

Does Industry-University-Research Cooperation Matter? An Analysis of Its Coupling Effect on Regional Innovation and Economic Development

The dislocation between regional innovation and economic development directly influences the economic effect of regional innovation. However, no in-depth researches have been made on how to solve this problem. Using data from Henan Province, China,employing geographical detector technology, this paper focuses on testing whether the industry-university-research cooperation can contribute to coordinating the relation between regional innovation and economic development. It is shown that: 1) the industry-universityresearch cooperation in Henan Province is increasing gradually, and the network presents a core-edge structure, and the coupling degree between regional innovation and economic development is spatially unbalanced, which is similar to the spatial distribution of the intensity of industry-university-research cooperation;2) as an important approach to effectively connect scientific researches with market demands, the industry-university-research cooperation can help form an interactive, interconnected, coupled and coordinated virtuous relation between regional innovation and economic development. Compared with the cooperation between organizations of the same type and the separate innovation of organizations, the improvement of the industry-university-research cooperation level can better coordinate the relation between regional innovation and economic development;3) the cooperative innovation model between enterprises and universities can better promote the coupling between regional innovation and economic development, compared with many industryuniversity-research cooperation models. For underdeveloped areas lacking local knowledge base, industry-university-research cooperation should be considered as a long-term development strategy, especially using the knowledge sources of external universities and scientific research institutions to enhance innovation capability and achieve economic growth.

Characteristics of mantle branch structure in western Shandong and its roles in minerogenesis and ore-controlling

This work deals with the characteristics of mantle branch structure in western Shandong Province, China, with respect to the distribution characteristics and ages of the regional strata, the development of ring-like and radial faults, the development of gently inclined detachment-slip structures in the axial part, mantle-source magmatic activities, regional petrology, petrochemistry and isotope geology. The study indicated that the N-W sharply plunged ductile shear zone in the region of western Shandong cuts through the mantle rocks detached from the deep-seated North China mantle sub-plume, hence leading to unloading in response to depressurization and thereafter the formation of anatexis magma. The intense and complete magmatic evolution series not only manifests a variation trend of alkalinity of magma from high to low and its intrusive depth from deep to shallow, but also reflects that the wall-rock alteration shows a general evolution trend from strong to weak. The evolution of mantle structure played an important role in controlling endo-mineralogenesis, accompanied with the rise of the country rocks. As a result, typical mantle branch structures were formed as observed in western Shandong. At the top of the mantle branch structure was developed an obvious detachment-tilt fault block, and some endogenic ores, at the same time, were uplifted onto the shallow levels.

晋西黄土区典型人工林土壤水分的垂直分布特征

【目的】探究晋西黄土区人工林恢复过程中0~500 cm土层土壤含水量垂直特征,为改善人工林土壤水环境,实现林水平衡提供理论依据。【方法】以晋西黄土区蔡家川流域5种典型人工林(刺槐Robinia pseudoacacia、侧柏Platycladus orientalis、油松Pinus tabuliformis、刺槐-侧柏、刺槐-油松)为研究对象,通过土钻烘干法测定0~500 cm土层土壤含水量,分析人工林土壤含水量的垂直特征。【结果】研究区典型人工林平均土壤含水量由大到小依次为侧柏、刺槐-侧柏、油松、刺槐-油松、刺槐,5种人工林土壤含水量差异显著(P<0.05),降水量及土壤质地是影响人工林土壤含水量的主要因素;在垂直方向上,人工林土壤含水量变异程度均为中等变异,变异系数随土层深度的增加呈减小趋势,约在360 cm土层形成稳定变化,人工植被主要影响0~360 cm土层内的土壤水,5种人工林中刺槐林地土壤水分变异程度最大,侧柏林地土壤水分最为稳定;采用有序聚类法将人工林土壤水分垂直层次划分为交换层、利用层、调节层和稳定层,不同林分间层次划分深度存在一定差异。【结论】研究区人工林可导致土壤含水量一定程度的减少,刺槐、油松、刺槐-油松林会加剧对深层土壤水分的消耗,其中刺槐林对深层土壤水分的消耗最为明显,建议在林业生态工程建设时,适当减少刺槐林面积,提高侧柏栽植比例。对现存土壤含水量较低的刺槐林,通过间伐降低林分密度,或将其改造为混交林,以期改善土壤水环境,实现林水平衡。

晋西黄土区不同密度刺槐林土壤有机碳组分及碳库特征

明晰不同林分密度下土壤有机碳组分含量及碳库特征,以期为确定刺槐林适宜人工造林密度和评价水土保持效益提供科技支撑。设置不同密度(700、1 500、1 800、2 400、3 000、3 500 plant·hm^(-2))刺槐样地,以荒草地为对照,分析0-40 cm土层土壤有机碳组分及变化规律,计算碳库活度指数(CPAI)、碳库指数(CPI)以及碳库管理指数(CPMI),解析不同密度刺槐林地土壤碳库变化,并探讨土壤理化性质对土壤有机碳及其组分变化的影响。结果表明:不同密度刺槐林地土壤有机碳及其组分的含量均随着土层深度的增加而减少,平均土壤有机碳(SOC)含量为:6.80 g·kg^(-1)(1 800 plant·hm^(-2))>5.01 g·kg^(-1)(1 500 plant·hm^(-2))>4.73 g·kg^(-1) (2 400 plant·hm^(-2))>4.17 g·kg^(-1) (3 000 plant·hm^(-2))>2.78 g·kg^(-1) (700 plant·hm^(-2))>2.68 g·kg^(-1) (3 500plant·hm^(-2))>0.52 g·kg^(-1) (CK)。随着刺槐人工林密度的增大,土壤有机碳组分及CPMI呈先增大后减小的趋势,中密度刺槐林分土壤有机碳组分含量及CPMI最大。与对照相比,0-40 cm土层,6种林分密度的土壤易氧化有机碳、稳定态有机碳含量、可溶性有机碳、颗粒有机碳和矿质结合态有机碳分别提高了77.3%-94.9%、55.8%-91.3%、86.0%-94.2%、81.4%-93.5%和79.8%-91.2%。6种林分密度土壤碳库管理指数均高于100%。相关关系分析表明土壤总有机碳含量与各有机碳组分均呈极显著正相关(P<0.010);冗余分析表明土壤全氮对土壤有机碳及其组分变化的解释率最大。因此,从森林土壤固碳功能而言,晋西黄土区刺槐人工林的适宜林分密度为1 800 plant·hm^(-2),该林分密度能较好提高土壤碳养分供给水平与碳库稳定性。

以湖南省中西部地区为研究区,选取地形地貌、地质条件、环境条件和人工活动4个方面15个因子构成滑坡易发性评价体系。首先,以2015—2022年发生的1 017个历史滑坡灾害数据为样本数据,采用信息量模型统计和分析影响该区域的滑坡因子重要度,结果表明该区域内地形湿度指数、土地利用类型、距道路距离、距河流距离和植被覆盖指数是影响滑坡发生的因子。然后,结合因子相关性分析,筛选其中14个因子纳入滑坡易发性分区分析,基于5种机器学习方法进行滑坡易发性建模和对比,结果表明随机森林方法在该区域针对相关的因子体系表现出的精度相对较高。最后,采用随机森林方法,按照低易发、较低易发、中易发、较高易发和高易发5个等级对研究区进行易发性分区制图,并与历史滑坡记录进行比对,结果表明易发性等级划定结果与滑坡密度基本吻合。该研究结果可以为湖南中西部地区滑坡灾害预测预报提供技术参考。

河南省数字经济与区域创新能力耦合协调分析测度

本文以河南省17个地级市(不含省辖县级市济源市)2016—2021年数据为研究样本,运用耦合协调度模型、Dagum基尼系数、数据地图等实证分析了各地级市数字经济和创新能力耦合协调发展水平以及空间分布演变特征。研究发现,河南省各地级市的数字经济、创新能力与耦合协调度整体稳定增长,但是全省耦合协调水平普遍较低。从地区发展来看,郑州市属于高度协调的第一梯队,洛阳市、南阳市属于第二梯队,分别在2018年和2021年达到高度磨合和低度磨合阶段,其他地级市属于第三梯队,处于高度拮抗状态。从区域联动性来看,近几年豫中、豫东、豫西、豫北和豫南几个区域耦合度呈现一定的空间聚集与带动效应,且区域间差异逐年减小,但是以郑州市为核心的豫中地区耦合协调度综合得分明显高于其他区域,地区之间的发展差异仍需引起重视。

SOTEM技术在豫西地区银多金属矿深部找矿中的应用

在豫西地区银多金属矿深部找矿工作中,采用电性源短偏移距瞬变电磁法(SOTEM),结合地质构造和物性特征,对豫西地区的银多金属矿进行了深部探测。通过对龙门店矿区和申家窑矿区的工程实例分析,结果表明SOTEM技术能够有效探测高阻和低阻地质体,尤其是在山区大探测深度的需求下,相较于传统的AMT技术,SOTEM技术施工更简单、勘探深度更大。在龙门店矿区,SOTEM技术成功揭示了与银铅矿体相关的高阻异常体;在申家窑矿区,SOTEM技术与AMT技术相互验证,均能有效探测层间拆离破碎带,但SOTEM技术在深部探测能力上更优。
