Three Types of Spatial Function Zoning in Key Ecological Function Areas Based on Ecological and Economic Coordinated Development: A Case Study of Tacheng Basin, China

Three types of spatial function zoning is an effective measure for regional environmental protection and orderly development.For ecological and economic coordinated development, spatial function zones should be divided scientifically to clear its direction of development and protection. Therefore, based on ecological constraints, a beneficial discussion would be about the key ecological function areas adopting the concept of ecological protection restriction and supporting socioeconomic development for spatial function zoning. In this paper, the researchers, taking Tacheng Basin, Xinjiang of China as an example, choose township as basic research unit and set up an evaluation index system from three aspects, namely, ecological protection suitability, agricultural production suitability, and urban development suitability, which are analyzed by using spatial analysis functions and exclusive matrix method. The results showed that: 1) This paper formed a set of multilevel evaluation index systems for three types of spatial function zoning of the key ecological function areas based on a novel perspective by scientifically dividing Tacheng Basin into ecological space, agricultural space, and urban space,which realized the integration and scientific orientation for spatial function at the township scale. 2) Under the guidance of three types of spatial pattern, the functional orientation and suggestions of development and protection was clearly defined for ecological protection zones,ecological economic zones, agricultural production zones, and urban development zones. 3) A new idea of space governance is provided to promote the coordinated and sustainable development between ecology and economy, which can break the traditional mode of thinking about regional economic development, and offers a scientific basis and reference for macro decision-making.

四川盆地PT1井区海相地层工程地质特征研究

PT1井区超深海相地层钻井过程中气侵和井漏频发,严重制约该区块的安全高效开发。文章基于有效应力法,利用最优化方法开展了海相地层孔隙压力评价;结合断层和裂缝发育程度探讨了PT1井区气侵和井漏纵横向分布特征。结果表明,受异常高压和裂缝发育程度的双重影响,气侵主要发生在龙潭组,占比达40%;井漏主要发生在筇竹寺组和灯影组,占总漏失量的80%以上。气侵与异常压力、裂缝发育程度、断裂情况等因素有关,异常高压是气侵内在的原因,而断裂带和发育的构造裂缝为气侵提供了必要条件。井漏层位和漏失量主要受一、二级大型断裂带控制,不同断裂带的影响具有显著的叠加效应,断裂带附近发育的构造裂缝为漏失提供了通道,距离F I7断裂越近越易出现漏失,且漏失量越大。研究成果为PT1井区钻井过程井下复杂预防和处理提供了科学支撑。

Integrated Approach to the Vital Mechanism Theory and Ant Colony Algorithm for Optimized Land Use Allocation: A Case Study of the Liangjiang New Area in Chongqing

Optimal allocation of land use is essential to promote regional economic and social development.However,research on such allocations in development zones is limited.This paper proposes a new land use allocation method for development zones and tests its feasibility.Based on prior research,this study predicts the developmental stage of a development zone and sets the objective functions and constraint conditions accordingly.This paper then measures the conversion relationship between the land use types in an unit according to the land use suitability results and the vital mechanism theory and uses the ant colony algorithm to construct a land use optimization model on the basis of this conversion relatonship.The model is then applied successfully to a case study of the Liangjiang New Area,Chongqing,China.The results show that the vital mechanism theory better reflects the relationship between land use types.The economic benefits increase 3.5 times and compactness improves by 46.5%between the initial year(2009)and the optimized year(2020),after the proposed model is applied.

Evaluation System and Method of Industrial Park Renewal:A Case Study of the Starting Area of Handan City

With the rapid development of urbanization,the industrial parks originally located in the suburbs are gradually incorporated into the urban center.Industries that fail to follow the transformation of urban economic development and are forced to close,or enterprises that move out without conforming to the environment,become a gray area within the city.Most of the existing assessments are conducting single assessment of some indicators,but than their actual benefits.Through the field investigation on the starting area of Handan Economic Development Zone,and the evaluation on the nature of land use,development intensity,investment and output,and idle land,inefficient land use in the park is identified.According to different evaluation results,different update and promotion methods are put forward.The research could provide a new evaluation method and idea for subsequent renewal and development of urban industrial parks.

普及化背景下跨省域高等教育欠发达片区问题及其解决策略

普及化高等教育必须实现区域协调和高质量发展。我国高等教育发展存在四个跨省域欠发达片区,主要表现在高等教育规模较小、高等教育重心偏低、高水平高校少和高等教育人口较少等方面。跨省域高等教育欠发达片区形成的原因,主要在于这些片区自然环境欠佳,经济发展滞后;远离政治经济中心,历史文化滋养不足和地处多省域交界,属于政府规划的盲点地带等。解决跨省域高等教育欠发达片区问题,应将其上升为国家战略,运用政策杠杆支持欠发达片区发展高等教育;建设跨省域发展协作机制,发挥协作机制联动作用;制定并实施欠发达片区“办学特区”政策,解决片区高等教育发展特殊问题;建立向欠发达片区“输血”机制,激发片区高等教育发展活力。

城镇密集地区国家级高新区发展模式与空间优化研究——以苏南五市国家级高新区为例

苏南城镇密集地区城乡功能叠加、空间构成复杂,同时也是长三角科技创新的核心地区。苏南国家级高新区作为二者的结合,其研究具有重要的意义和价值。本文以苏南五市的国家级高新区为研究对象,分析其发展特征、空间特征和经济特征,并总结国家级高新区典型的空间组织模式,进而提出空间优化的重点。本文认为:(1)从现状特征来看,苏南地区的国家级高新区经历了三个发展阶段,空间上多布局于沿长江片区及沪宁通道沿线,其发展规模与其所在城市整体规模、能级呈现正相关关系,已初步形成差异化产业发展定位,但园区创新能力存在较大差距;(2)从空间发展特征来看,苏南地区9个国家级高新区可以概括为三种典型空间类型,即依托城市高能级、不断扩展生长的“中心延伸型”,与生态资源、农业资源相伴相生的“边缘拓展型”,依附乡镇空间资源、互惠互促发展的“跳跃生长型”,各类型在空间范围分布、空间组织模式、与主城区的关系等方面具有明显差异;(3)从空间优化的角度,建议进一步处理好“有序蓝图”与“无序基底”的关系,优化空间组织模式,进一步挖掘出“整体有机”与“高级灰度”的内涵,深化空间塑造理念,进一步强化多元共治与政策创新,实现管理机制体制优化。

基于主体功能区的长江经济带绿色发展评价与问题区域识别

长江经济带已成为我国推进绿色发展的重要阵地。基于主体功能区视角,构建以水系统为纽带的长江经济带绿色发展评价指标体系,采用综合加权法、空间自相关、耦合协调度模型等方法探究2018年长江经济带130个城市绿色发展及各子系统耦合协调水平的空间格局,并对绿色发展的问题区域进行分类识别。结果表明:(1)长江经济带绿色发展水平呈由下游、中游至上游递减趋势;各主体功能区绿色发展指数表现为优化开发区>限制开发区>重点开发区。(2)绿色发展各子系统耦合协调度值位于0.365—0.656之间,多处于濒临失调和勉强协调的临界区间,耦合协调水平整体偏低。(3)从长江经济带整体来看,长江中上游地区绝大部分城市绿色发展主要受资源利用和产业发展水平偏低,及由此带来的生态和生活问题限制,且长江中上游地区各省会或直辖市对区域内其他城市绿色发展带动能力不足。从主体功能区视角来看,优化开发区以生态问题为主,仅上海和嘉兴两市;重点开发区以生态和生产问题为主,集中于武汉都市圈和成渝双城经济圈内部;限制开发区以生产和生活问题为主,主要位于省际边界型城市地区。最后综合问题识别结果,分别对长江经济带各主要问题区域绿色发展路径提出具体对策建议。

农村人口老龄化对农业高质量发展的影响

基于2004—2020年中国内地30个省市面板数据,在运用熵值法测算出我国农业高质量发展水平的基础上,通过动态面板和门槛效应模型对农村人口老龄化促进农业高质量发展的效果和机制进行了实证检验。研究结果表明:农村人口老龄化能够显著提高农业高质量发展水平,其促进效应在粮食主产区内要强于产销平衡区内,而在主销区内,这一促进效应则并不显著。对农业高质量发展分维度异质性分析后发现:农村人口老龄化通过改善农业高质量发展中农业发展水平、资源条件、经济条件以及技术条件,促进农业高质量发展水平的提高;通过抑制环境条件的改善,阻碍农业高质量发展水平的提高。最后,门槛效应检验结果表明:农村人口老龄化对农业高质量发展的促进效应会随着农业高质量发展水平的提高而得到进一步的增强。

富满油田超深碳酸盐岩油气藏走滑断裂带有利储层发育区研究

塔里木盆地富满油田超深海相碳酸盐岩油气资源丰富。受埋藏深度大、构造活动强的影响,其碳酸盐岩有利储层难以预测,严重制约富满油田的勘探开发。该文利用地震资料、测录井及试油资料,明确了走滑断裂纵向分层、平面分段的特征,结合走滑断裂破碎带的结构,探讨了不同特征走滑断裂带下有利储层的发育位置。研究表明:压扭段断裂有利储层发育在主干断裂中部;张扭段断裂有利储层位于两条主干断裂之间垂向断距较大一侧;走滑平移段断裂有利储层位于整个主干断裂带;复合段断裂有利储层为主干断裂附近垂向断距较大一侧。勘探结果证实,四种类型走滑断裂有利储层的发育位置与研究结果一致。该研究对富满油田碳酸盐岩有利储层的预测和井位部署具有借鉴意义。
