The tropical cyclone boundary layer(TCBL)connecting the underlying terrain and the upper atmosphere plays a crucial role in the overall dynamics of a tropical cyclone *** tropical cyclones approach the coastline,the wind field inside the TCBL makes a sea-land transition to impact both onshore and offshore *** better understanding of the wind field inside the TCBL in the sea-land transition zone is of great *** this end,a semiempirical model that integrates the sea-land transition model from the Engineering Sciences Data Unit(ESDU),Huang's refined TCBL wind field model,and the climate change scenarios from the Coupled Model Intercomparison Project Phase 6(CMIP6)is used to investigate the influence of climate changes on the sea-land transition of the TCBL wind flow in Hong *** specifically,such a semiempirical method is employed in a series of Monte-Carlo simulations to predict the wind profiles inside the TCBL across the coastline of Hong Kong under the impact of future climate *** wind profiles calculated based on the Monte-Carlo simulation results reveal that,under the influences of the most severe climate change scenario,slightly higher and significantly lower wind speeds are found at altitudes above and below 400 m,respectively,compared to the wind speeds recommended in the Hong Kong Wind Code of *** findings imply that the wind profile model currently adopted by the Hong Kong authorities in assessing the safety of low-to high-rise buildings may be unnecessarily over-conservative under the influence of climate *** the other hand,the coded wind loads on super-tall buildings slightly underestimate the typhoon impacts under the severe climate change conditions anticipated for coastal southern China.

Wuhan University Journal of Natural Sciences 2017年第5期22卷 402-410页

作者： XIE Mingxia wang jiayao YANG Aiming CHEN Ke Changjiang Spatial Information Technology EngineeringCO.LTD Wuhan 430019HubeiChina Institute of Surveying and Mapping Information Engineering UniversityZhengzhou 450052HenanChina

Establishing a reasonable evaluation index system is the basis and premise for the scientific evaluation of geographic national conditions. By analyzing the DPSIR model and its correlation and relation with the evaluation index system, the indexes for geographic national conditions were selected from the aspects of resources, ecology, environment, economy, society, etc to build an evaluation index system for geographic national conditions that consists of three hierarchies： index, criterion, and target levels. Furthermore, the index system was analyzed in terms of index integrity, low overlapping of elements, non-existence of isolated indexes, hierarchy of index system, etc., for the purpose of demonstrating that the DPSIR model-based evaluation index system for geographic national conditions meets the principles of index system establishment.

本文利用景观指数、核密度估计、土地转移矩阵和地理探测器的方法,以城市群为研究单元,分析了1980-2020年黄河流域农村居民点的时空演变特征和驱动力。结果表明:①农村居民点总体用地规模在不断扩大,主要由旱地转换而来;中原城市群农村居民点密度变化最大;除关中平原城市群外,其他6个城市群农村居民点的形状变得更为规则。②农村居民点空间分布为“东南部聚集,西部、北部较分散”,呈现出更为密集的发展趋势,中原城市群变化最为明显。③农村居民点主要分布在高程1 km以下、距河流2~5 km处,其规模与距道路的距离成反比;道路是影响兰西、宁夏沿黄、关中平原和山东半岛城市群居民点分布的主要因素,而高程是影响呼包鄂榆、晋中和中原城市群居民点分布的主要因素。
