Spatial prediction of landslide for Badong County in the Three Gorges reservoir district

By using the landslide risk evaluating model and the advantages of GIS technology in image processing and space analysis, the relative landslide hazard and risk evaluating system of the new county site of Badong is built up. The system is mainly consisted of four subsystems： Information management subsystem, hazard as- sessment subsystem, vulnerability evaluation subsystem and risk prediction subsystem. In the system, landslide hazard assessment, vulnerability evaluation, risk predictions are carried out automatically based on irregular units. At last the landslide hazard and risk map of the study area is compiled. During the whole procedure, Matter-Element Model, Artificial Neural Network, ancl Information Model are used as assessment models. This system provides an effective way for the landslide hazard information management and risk prediction of each district in the Reservoir of Three Gorge Project. The result of the assessment can be a gist and ensure for the land planning and the emigration project in Badong.

The Differences between County,County-level City and Municipal District in the System of Administrative Divisions in China

Administrative division is an important means of political power reorganization and management,resource integration and optimal allocation,which profoundly shapes the spatial layout of urban development in China.To clarify and compare differences between counties,county-level cities and municipal districts is the primary premise for the study of administrative division and urban development.This paper analyzes the institutional differences between counties and county-level cities,as well as counties,county-level cities and municipal districts,from the aspects of organizational structure,urban construction planning,land management,finance,taxation and public services.The research shows that the establishment of counties,county-level cities and municipal districts adapt to different levels and stages of economic and social development,and the conversion from county to county-level city and the conversion from county(or county-level city)to municipal district are both important transformation ways to change their administrative systems,which has different management system and operation pattern.At the same time,the transformation of county-level administrative region is also a“double-edged sword”,we should think about the administrative system as a whole to decide whether it should be adjusted,and effectively respond to the actual needs of local economic and social development.

Dual-objective pattern optimization method for land suitability zoning in mountain counties

As the basic administrative unit of China,counties have grown rapidly in recent years in the context of rapid urbanization,especially for counties located in mountainous areas.The drastic changes in land in mountainous areas can easily cause irreversible damage to the sensitive ecological environment.Through the dual-objective suitability zoning of ecological and construction balance,regional sustainable land use patterns can be realized.In this study,Hantai District in Southern Shaanxi province,China,was chosen as the research area aiming at creating a balance between ecological supply and the development of construction in spatial planning.A dual-objective process evaluation system for ecological protection and construction development was proposed with 15 resistance factors selected from three attributes:natural ecology,economic society,and policy.The minimum resistance surface discrimination methods for ecological land and construction development land were proposed based on vertical space superposition and horizontal minimum cumulative resistance models.Finally,the land in Hantai District was divided into four development grades from the optimal angle of dual goals,i.e.,the construction core zone being 134.56 km^(2),the suitable construction zone 115.77 km2,the ecological buffer zone 153.74 km^(2),and the ecological control zone 151.93 km^(2),using the method combining resistance difference and threshold division.In addition,the development direction of each town under jurisdiction was identified.This study compensates for the deficiency of traditional methods that evaluate land only from a single vertical or horizontal process.

撤县设区、空间一致性与县域经济发展

县域经济是我国实现城镇化发展的主战场。本文利用夜间灯光数据代理县域经济发展水平,突破统计数据受制于行政区划的空间限制,获得空间一致且跨时间可比的县域经济衡量指标。这不仅可避免因使用统计数据可能导致的可塑性面积单元问题,还可以同时分析“撤县设区”对县(市)和市辖区的影响,为“撤县设区”的研究提供更细致完整的图景。研究发现:“撤县设区”改革无论对被撤并县(市),还是对原市辖区的经济发展均未产生显著影响。原因在于,尽管“撤县设区”能够促进县域企业吸收更多人力资本,但却显著降低了企业的固定资产净投资和全要素生产率,这在一定程度上解释了为何“撤县设区”改革不能显著推动县域经济发展的原因。

为什么国家严控撤县设区:基于粮食安全的新解释

撤县设区是我国推进新型城镇化建设的重要行政区划调整政策。但2021年以来,国家多次表态要严控撤县设区。将撤县设区政策视为准自然实验,基于2000—2019年县域经济社会数据,运用多期DID、PSM-DID、CMP模型、中介效应模型等分析了撤县设区政策对粮食生产和粮食安全的影响及作用机制,从粮食安全视角对国家严控撤县设区的合理性进行了论证。研究发现:首先,撤县设区政策不利于粮食生产和粮食安全,这一结论在更换回归模型、更换被解释变量、调整样本量等检验后仍然稳健,而且这种负面影响存在长期性;其次,撤县设区政策通过农业生产要素重新配置和“政府注意力”转移两个方面对粮食安全产生负面影响;最后,这种负面影响还存在地区异质性,撤县设区对非粮食生产核心区的负面影响更加显著,导致粮食安全责任进一步失衡。建议谨慎推进撤县设区,平衡不同省份粮食安全责任,有序推进县域粮食综合生产能力提升。

湖南省创新型县(市、区)创新能力评价——基于综合赋权的障碍因子诊断

试论北宋熙宁年间东南诸路的增设新县现象

王安石变法期间,北方的河北、河东、永兴军等路为节省地方行政成本,裁撤了大量县,而东南各路却没有出现这种情况。后来陈瓘指称王安石对北方和南方采取双重标准,即主张在北方大量撤县的同时,却在南方析置新县。经过考察可知,王安石变法期间,东南各路的新设县数量很少。而自五代宋初以来,东南各路却多有新设县。北宋在东南各路增设新县,一方面是平定南方各政权后,在新纳土地上调整行政区;另一方面是由于人口增长,经济发展,地方事务增多所致。王安石的判断实际反映了当时东南经济迅速发展,人口和地方事务急剧增加的时代背景。

行政区划调整与城市空间结构演化——基于撤县设区的视角

在新型城镇化建设对城市紧凑集约发展提出更高要求的背景下,探讨行政区划调整对城市空间结构的影响具有重要意义。基于2000—2016年全国范围内演进的撤县设区数据,深入考察了撤县设区带来的城市空间结构演化效应的研究发现:(1)撤县设区促使了城市空间形态松散化和内部低密度发展,该结论在考虑多种指标、方法以及政策滞后效应之后仍成立。(2)撤县设区政策对东部城市的空间结构松散化影响更强,且不利于其发挥中心集聚优势;相比于建设规制较弱的城市,规制较强的城市受到撤县设区对城市空间结构分散化的影响更为显著。(3)进一步研究表明,自主选择型撤县设区对城市空间结构分散化的影响更加明显,而顺应融入型撤县设区则会在一定程度上促进城市空间结构趋于紧凑化。

余杭区乡村古树资源分析及古树公园建设策略

以杭州市余杭区乡村古树及其后备资源为研究对象,采用文献数据统计和实地踏查相结合的方法总结了余杭区乡村古树资源的自然条件特征,分析了古树资源和地区人文条件、经济条件及区位条件的关系,并通过对不同因子进行赋值以评估不同乡村建立古树公园的优先级。研究表明:(1)余杭区乡村现存古树621株,其中一级古树22株,古树后备资源777株,隶属于25科45种,古树及后备资源数量随树龄的增加呈下降趋势;(2)各地区的林业发展、旅游发展、距杭州市城区距离对乡村古树的保留起到促进作用,同时也影响了古树资源的群落组成;(3)百丈镇半山村、鸬鸟镇山沟沟村、径山镇径山村、径山镇小古城村、瓶窑镇塘埠村和中泰街道紫荆村的综合评估等级最高,建议在这些地方优先建立乡村古树公园。提出构建古树公园体系、挖掘乡村人文历史、科学智慧保护措施、激发多元保护治理四个方面的策略,以期守护好余杭区乡村古树资源,传承乡村古树生态文明,促进乡村古树公园建设,助力乡村振兴。
