On the basis of the city development, principles of urban forest layout were put forward, and the overall structure of "one core, one belt, two rings, three corridors, four groups, fi ve windows, and multiple bases" was given for the construction of urban forest in coastal landscape cities, in addition, the effect and feasibility of the layout were analyzed.     

城市森林斑块对温湿度的影响研究

为了量化城市森林斑块对周边环境温湿度的影响,为城市森林建设布局提供理论依据,对南昌市的2处森林斑块的温湿度影响进行测定。结果表明,森林斑块对周边温度的影响差异显著,在斑块中心与斑块外围1 km距离的差异在4℃左右,有着明显的降温效果;而对于湿度的影响则不明显。因此,城市森林建设应充分考虑其实际影响范围,合理布局。

Strategies for Improving the Overall Environmental Quality of Rivers Based on “Renovation and Restoration” Concept: A Case Study of Landscape Planning of Linjiang River,Yongchuan District,Chongqing City

The concept of "renovation and restoration" marks the transformation from urban and rural planning and construction to intensive development mode and to quality improvement stage.The environmental imbalance problem of emphasizing development and neglecting ecology in the past has become the focus of the current urban quality improvement stage.Rivers are related to the origin,development and evolution of cities,affect the layout,transportation and environment of cities,and bear the culture,economy and characteristics of cities.Taking the Linjing River of Yongchuan in Chongqing as an example and taking the concept of "renovation and restoration" as the guidance of the design of the overall environmental quality improvement of the river,this study analyzed and summarized the problems to be solved in the improvement of the environmental quality of the river based on the four river environmental impact factors of water pollution,water resource supply and demand,ecological environment and shore water waterfront type and the strategies of optimizing the aquatic environment management,constructing the ecological landscape pattern,shaping the regional cultural landscape and combining the economic development along the river were put forward in order to improve the overall environmental quality of Linjiang River and provide reference for relevant planning and design.     

Landscape Pattern Optimization of Chengdu Based on Modern Garden City

TOptimization of regional landscape pattern is significant for improving function and value of ecosystem,and restraining the expansion of urban layout.Taking Chengdu City for example,this paper applied RS and GIS techniques,landscape indexes and ecological service function evaluation to further analyze the temporal and spatial characteristics of landscape pattern and spatial differences of regional ecological functions,and on this basis,identified the spatial distribution of ecological source lands.Based on the long-term objective of building Chengdu into a modem garden city,this paper applied the accumulative cost distance model and introduced garden city theory to construct regional ecological corridors and ecological nodes,and explored the approaches of optimizing landscape pattern of modem garden city.The results showed that a great deal of arable land has been transferred to construction land in the urbanization;intensity of regional ecological functions showed obvious spatial differences;ecological source lands were mainly distributed in the Longmen Mountain,the Qionglai Mountain,the Changqiu Mountain and the Longquan Mountain;according to actual conditions of the study area,the road ecological corridors,river corridors and agricultural corridors in the layout of "four rings and six radial corridors" were constructed;ecological nodes dominated by intersection,wetland and forest park were formed.This research method and results are significant references for building Chengdu into a modem garden city     

重庆市永川区土地利用空间格局变化模拟

为了研究快速城市化过程中县级尺度土地利用结构特征,从而更精确把握土地利用与覆被变化的动态过程。将GIS技术与CLUE-S模型结合研究重庆市永川区土地利用空间格局的变化。结果表明：永川区2000—2010年土地利用类型变化均以森林和农田为主,各期占总面积90%以上。从2000—2010年城镇面积显著增加,增加了16.11%,且2005—2010年城镇面积变化程度比2000—2005年变化更为剧烈。森林面积在10年间少量增加。10年间农田面积减少了1660 hm2。对永川区土地利用变化设定3种情景进行模拟,并对预测结果进行比较分析。由此得出：在快速城市化的驱动下,永川区土地利用景观格局变化以森林和农田为主,城镇面积大幅度增加,森林面积也呈现增加趋势。相应地农田面积减少。生态保护情景模式下对生态环境有保护作用的土地利用类型有较好的调控效果。     

Ecological Planning and Design of Urban Green Space System of Sanya City

The construction of International Tourism Island has accelerated the development of Sanya City. The population aggregation and the external extension of urban area have brought a lot of negative effects, such as discontinuities of green space matrix, dysfunction of green wedge permeation, deficiency of eco-corridor, structural imbalance of green space system and so on. The overall layout of Green space system known as "One Belt Three Bays, One Core Six Towns, Two Axes Three Wedges, Two Net Synchronous-construction" strengthens the eco-connection among different groups and green space in central area of the city, and realizes the collaborative construction of both resource corridor and landscape corridor. The eco-layout of green core, green corridor and green patch helps keep the integrity of large vegetation patches, enhances the eco-connection of different types of green space and improves finger-shaped network of urban green space. The most efficient way to promote the circulation of urban ecosystem and the positive development of Sanya City is to plan multilevel and three-dimensional eco-space structure and maximize ecological benefits of green space system.     

长株潭地区土地利用/覆被变化的时空特征研究

为了揭示长株潭地区城市化快速发展时期的土地利用的数量变化和空间变化特征,加强土地空间管制和促进土地资源可持续利用,以1986年、1995年、2005年3期土地利用/覆被现状数据为基础,结合GIS技术,对长株潭地区的土地利用/覆被变化时空特征进行研究。结果表明：（1）林地和水田是长株潭地区的优势地类。这段时期内城镇建设用地和农村居民用地面积持续增加,水田面积持续减少。其他地类面积波动变化;（2）各种土地利用类型之间相互转换。大部分水田、旱地、林地、灌木林地和水域转换成了城镇建设用地。新增的农村居民用地主要由水田转换而来。城镇建设用地的增长呈现出依附原有建设用地增长和跳跃式的增长2种方式;（3）长株潭地区土地利用数量变化存在明显的区域差异。长沙市区、株洲市区和湘潭市区等地的土地利用类型的相对变化率较大;醴陵市、炎陵县和茶陵县等地的土地利用类型的相对变化率较小;（4）长株潭地区土地利用变化的年均变化速度不是很快。正向变化的土地利用类型有城镇建设用地、农村居民用地、水域和草地,其中增长变化最快的是城镇建设用地;其余土地利用类型负向变化,其中减少变化最快的是果园。研究认为,长株潭一体化进程的深入,城市化水平的提高和差异是长株潭地区土地利用发生时空变化和区域差异的主要原因。     

Urban Design Strategy Research Based on the Concept of Sponge City: A Case Study of Renbei District in Chengdu

Cities are currently confronted with many urban problems, such as water shortages, water quality pollution, floods, and the loss of habitats of aquatic organisms, and badly in need of a more comprehensive solution. In this context, the concept of "sponge city" is proposed. This paper, based on the theory of sponge city and low impact development, elaborated the origin, development, connotation, and construction method of "sponge city" concept. In this paper, the urban design scheme of Renbei District in Chengdu was taken for example to analyze the geographical environment and climate characteristics of Chengdu and explain the formation and verification of the scheme. It is considered that the "sponge city" is different from the traditional urban infrastructure. It is essentially an ecological approach. Its core is to build a cross-scale urban water ecological infrastructure to comprehensively solve the prominent water-related problems of urban and rural areas in China.     

Exploration of Living Modes for Small-scale Community Endowment

The aging and the urban development bring a great challenge to the residential facilities of the elderly community. By exploring the layout and current situation of the elderly residential facilities in Chengdu City, this paper stressed the key points in the layout of various facilities at the macro scale. Through the deep investigation of residential districts, the paper explored the community endowment mode that is between the organization support and home-based care for the aged, and proposed 3 modes on the basis of "visiting, day care and short-stay". Considering the specific needs of the aged and the compound modes, compound community endowment mode was put forward as the future development direction of community endowment to contribute to the construction of the overall social endowment system.

GIS-based Village Layout Planning in Towns: A Case Study of Fengyang Town,Fenxi County,Jiangxi Province

Village layout planning is a fundamental work in the construction of beautiful countryside, and also a global work involving vital interests of vast farmers. Taking Fengyang Town of Fenxi County, Jiangxi Province for example, this paper applied Arc GIS to analyze natural facors, social economy, and construction factors quantitatively by evaluating development and construction conditions of each village comprehensively from the perspective of urban-rural integration. Classifying the villages into 4 types, namely urban reform type, concentrated development type, controlled construction type and relocation type, this paper tried to guide the scattered rural settlements to the intensive development.
