Creation of "Regional Characteristic" in Planning and Design of Farmers' Residential Area at the South of Lower Reaches of the Yangtze River

After analysis of location feature of the south of lower reaches of Yangtze River and its construction of urban and rural integration,the paper pointed out harmonious combination between natural and artificial factors had been neglected in planning and design of farmers' residential area at the south of lower reaches of Yangtze River,"regional characteristic" losing,residential area in the form of "city community" and buildings in European style.In view of these problems,relevant planning and design thoughts and methods had been proposed as to how to create "regional characteristic" from the perspective of planning,architecture and landscape design.It discussed with emphasis the importance of construction base type and combination of environment with residential area construction;inspirations and design methods obtained from traditional architectures;and the content of landscape overall planning and specific design.It was hoped to enlighten designers to shoulder social and historical responsibility,make exploration unremittingly,and construct beautiful homelands for people.

Exploration of the “Living” Protection of Historic Blocks in South of the Yangtze River——A Case Study of Ancient Shajiabang Town, Changshu City

Historic blocks that focus only on protection of tangible constructed environment have shown various disadvantages and gradually lost their originality, according to the investigation. Protection of historic blocks should attach more importance to maintaining original lifestyles and community customs, protecting intangible contents and cultural diversity. The authors proposed that protection of historic blocks should follow the principle of "putting protection and repair on the top priority, using reasonably" and stress the "living" protection. There are three patterns of "living" protection, specifically, joint participation of local residents, construction of education base, moderate tourism development. Vitality of local economy can be enhanced and social humanistic environment protected effectively by improving the locals' living environment, so as to show true care for the people living in the historic block, and bring historic blocks to the real life.

Variations and net transport of dissolved inorganic nutrients in the South Passage of the Changjiang(Yangtze River) Estuary

Dissolved inorganic nutrient elements were analyzed from the samples collected in the South Passage of the Changjiang (Yangtze River) Estuary in March 2003, including NH4+, NO3-, NO2- and PO43-. The water samples were collected with a Niskin sampler hourly at the near-surface, middle and near-bottom depths at the three stations -A1, A2 and A3-during two complete tidal cycles of neap tide and spring tide. Results showed that 1) the concentrations of NH4+, NO3- and NO2- were a little higher respectively during the neap tide than those during the spring tide, while PO43- showed an opposite trend, and each was higher in the ebb tide than in the flood tide, either for the neap tidal cycle or the spring tidal cycle; 2) higher stratification of the nutrients existed obviously in this area, with the concentrations of which increased from the bottom to the surface, especially for NH4+ and NO3-; 3) the coefficient of variation (C.V.) values of all dissolved inorganic nutrients varied from 4.06% to 36.8% beyond different influences of the tidal current and Changjiang runoff; 4) with increasing suspended matter in the water column, the concentrations of PO43- became lower in the filtered water; and 5) the total transport of each tidal cycle was much more in the spring tide than in the neap tide, and the positive values indicated that the nutrients had been exported to the East China Sea. Studies on the variations and net transport of dissolved inorganic nutrients in the South Passage of the Changjiang Estuary will provide the scientific basis for the study of the mechanism of red tide in the East China Sea.

近代江南地区丝织产业发展与当代创新需求

中国素有“丝国”之称,“丝”也在很多层面上加强了中国与世界文明的联系。江南地区的丝织业大约从宋代起,开始打破原有的中国丝织业三大中心格局,至明代成为我国最重要的丝织产业聚集地。近代以来,伴随西方机械生产设备和洋商涌入,江南丝织业无论是其原产业面貌或是生产经营方式,都发生了巨大变化,并一直延续至今。文章将对近代以来江南丝织产业的发展脉络进行梳理,并对当代丝织业所面临的新时代需求进行探讨。

联合申遗导向下的江南水乡古镇文化遗产价值评价

文化视域下《望江南·超然台作》的创作动因

知密时期是苏轼词创作的重要转型期,除“密州三曲”的杰出成就外,《望江南·超然台作》也是不可忽视的力作。这首作品一改以往清明节序词沉重哀伤的格调,呈现出清新旷达的风貌,从另外一个侧面体现了苏轼密州词创作的创新性和多元性。究其原因,苏轼依《望江南》词调创作该词明显是受中国文人追慕“江南”文化情结的影响,而其轻松愉快的风格则体现了苏轼对宋代清明节序词重享乐表达模式的接受,而其中洋溢的乐观旷达思想则是苏轼对密州地区多元融合地域文化消化吸收后的智慧结晶。

长江口南支长江江豚栖息地水生生物群落结构

为探究长江口长江江豚的栖息地选择偏好性,根据2022年夏季和秋季长江口南支长江江豚栖息地的水生生物调查数据,采用相对重要性指数、多样性指数以及丰度/生物量曲线(ABC曲线)等方法,研究分析了该水域水生生物多样性和群落结构特征。结果显示:(1)2022年夏季共采集水生生物9种,优势种为长吻鱼危(Leiocassis longirostris)、安氏白虾(Palaemon annandalei)和光泽黄颡鱼(Pelteobagrus nitidus),秋季共采集水生生物13种,优势种为河蚬(Corbicula fluminea)、长吻鱼危和安氏白虾;(2)通过多样性指数发现,秋季该水域的水生生物多样性水平整体高于夏季,夏季东风西沙水域的多样性水平高于青草沙水域,秋季则相反;(3)ABC曲线结果表明,夏季水生生物群落处于未干扰状态(W=0.196),秋季水生生物群落则处于严重干扰状态(W=-0.069)。结果表明:长江口南支长江江豚栖息地水域水生生物多样性水平仍较低,群落结构特征和优势种存在明显季节性差异,群落稳定性较低。水域内可供长江江豚选择的饵料种类较少且资源量较低,建议加强对该区域水生生物资源的养护管理。

The Relationship of Land-Ocean Thermal Anomaly Difference with Mei-yu and South China Sea Summer Monsoon

Based on the NCEP/NCAR reanalysis data for the period of 1948-2004 and the monthly rainfall data at 160 stations in China from 1951 to 2004, the relationships among the land-ocean temperature anomaly difference in the mid-lower troposphere in spring （April-May）, the mei-yu rainfall in the Yangtze River- Huaihe River basin, and the activities of the South China Sea summer monsoon （SCSSM） are analyzed by using correlation and composite analyses. Results show that a significant positive correlation exists between mei-yu rainfall and air temperature in the middle latitudes above the western Pacific, while a significant negative correlation is located to the southwest of the Baikal Lake. When the land-ocean thermal anomaly difference is stronger in spring, the western Pacific subtropical high （WPSH） will be weaker and retreat eastward in summer （June-July）, and the SCSSM will be stronger and advance further north, resulting in deficient moisture along the mei-yu front and below-normal precipitation in the mid and lower reaches of the Yangtze River, and vice versa for the weaker difference case. The effects and relative importance of the land and ocean anomalous heating on monsoon variability is also compared. It is found that the land and ocean thermal anomalies are both closely related to the summer circulation and mei-yu rainfall and SCSSM intensity, whereas the land heating anomaly is more important than ocean heating in changing the land-ocean thermal contrast and hence the summer monsoon intensity.

Observational and Modeling Studies of Impacts of the South China Sea Monsoon on the Monsoon Rainfall in the Middle-Lower Reaches of the Yangtze River During Summer

Based on the ERA-40 and NCEP/NCAR reanalysis data,the NOAA Climate Prediction Center＇s merged analysis of precipitation（CMAP）,and the fifth-generation PSU/NCAR Mesoscale Model version 3（MM5v3）,we defined a monsoon intensity index over the East Asian tropical region and analyzed the impacts of summer（June-July） South China Sea（SCS） monsoon anomaly on monsoon precipitation over the middle-lower reaches of the Yangtze River（MLRYR） using both observational data analysis and numerical simulation methods.The results from the data analysis show that the interannual variations of the tropical monsoon over the SCS are negatively correlated with the southwesterly winds and precipitation over the MLRYR during June-July.Corresponding to stronger（weaker） tropical monsoon and precipitation,the southwesterly winds are weaker（stronger） over the MLRYR,with less（more） local precipitation.The simulation results further exhibit that when changing the SCS monsoon intensity,there are significant variations of monsoon and precipitation over the MLRYR.The simulated anomalies generally consist with the observations,which verifies the impact of the tropical monsoon on the monsoon precipitation over the MLRYR.This impact might be supported by certain physical processes.Moreover,when the tropical summer monsoon is stronger,the tropical anomalous westerly winds and positive precipitation anomalies usually maintain in the tropics and do not move northward into the MLRYR,hence the transport of water vapor toward southern China is weakened and the southwest flow and precipitation over southern China are also attenuated.On the other hand,the strengthened tropical monsoon may result in the weakening and southward shift of the western Pacific subtropical high through self-adjustment of the atmospheric circulation,leading to the weakening of the monsoon flows and precipitation over the MLRYR.
