However, the long-term evolution of lakes in a certain megacity and the heterogeneity of the spatial relationship between related influencing factors and lake changes are rarely discussed. The evolution of 58 lakes in Wuhan, China from 1990 to 2019 was analyzed from three aspects of lake area, lake landscape, and lakefront ecology, respectively. The Multi-Scale Geographic Weighted Regression model (MGWR) was then used to analyze the impact of related influencing factors on lake area change. The investigation found that the total area of 58 lakes decreased by 15.3%. A worsening trend was found regarding lake landscape with the five landscape indexes of lakes dropping; in contrast, lakefront ecology saw a gradual recovery with variations in the remote sensing ecological index (RSEI) in the lakefront area. The MGWR regression results showed that, on the whole, the increase in Gross Domestic Product (GDP), RSEI in the lakefront area, precipitation, and humidity Citation: Wen, C.; Zhan, Q.; Zhan, contributed to lake restoration. -

5.8 VERIFICATION OF WIND FIELD RETRIEVAL OF DOPPLER RADAR VELOCITY-AZIMUTH PROCESSING METHOD Zheng Yongguang1 Liu Shuyuan1 Bai Jie2 Tao Zuyu1 (1 Department of Atmospheric Sciences, School of Physics, Peking University, Beijing 100871, P. R. China; 2 Beijing Aviation Meteorological Institute, Beijing 100085, P. R. China) 1 PRINCIPLE OF VAP METHOD direction and the radar beam. The VAP (Velocity-Azimuth Processing) method was put forward for retrieving the horizontal wind field from single Doppler radar data by Tao Zuyu (1992). Assume that the horizontal wind vectors are uniform in L a very small azimuth interval (i. e., the local uniformity of wind field) and neglect the vertical fall speed of the r L’ particles of low elevation scan, the formula of horizontal wind retrieval based on the distribution of Doppler velocity profiles with azimuth are as follows Figure 1 A schematic diagram of the relation (see Fig. 1): between the wind vectors and the radial velocities on Wind speed: local uniform wind assumption. v − v v = hr1 hr 2 , 2sinα sin ∆θ Because spatial and temporal resolutions of the Wind direction: Doppler radar data are higher than all of other winds v − v observations, it is difficult to obtain the detail tanα = − hr1 hr 2 cot ∆θ = an vhr1 + vhr 2 information of wind field for objectively evaluating the results derived by VAP method.

In fact, spatial planning system of China is Abstract—“National Territorial Planning (2016-2030)” was not perfect. It is a crucial problem that land resources have been issued by the State Council of China in 2017. As an important unordered and decentralized developed and overexploited so initiative of putting it into effect, territorial planning at provincial level that ecological space and agricultural space are seriously makes overall arrangement of territorial development, resources and squeezed. In this regard, territorial planning makes crucial environment protection, comprehensive renovation and security system construction. Hubei province, as the pivot of the “Rise of attempt to realize the "Multi-Plan Integration" mode and Central China” national strategy, is now confronted with great contributes to spatial planning system reform. It is also opportunities and challenges in territorial development, protection, conducive to improving land use regulation and enhancing and renovation. Territorial spatial pattern experiences long time territorial spatial governance ability. evolution, influenced by multiple internal and external driving forces. Territorial spatial pattern is the result of land use conversion It is not clear what are the main causes of its formation and what are for a long period. Land use change, as the significant effective ways of optimizing it. By analyzing land use data in 2016, this paper reveals present status of territory in Hubei. Combined with manifestation of human activities’ impact on natural economic and social data and construction information, driving forces ecosystems, has always been a specific field of global climate of territorial spatial pattern are then analyzed. -

Planning Strategy and Practice of Low-Carbon City Construction , 46 Th ISOCARP Congress 2010
Zhang Wentong, Planning Strategy and Practice of Low-carbon City Construction , 46 th ISOCARP Congress 2010 Planning Strategy and Practice of Low-carbon City Construction Development in Wuhan, China Zhang Wentong Yidong Hu I. Exploration on Planning of Low-carbon City Construction under the Global Context The concept of low-carbon is proposed in the context of responding to global climate change and advocating reducing the discharge of greenhouse gases in human’s production activities. While in the urban area, the low-carbon city is evolved gradually from the concept of ecological city, and these two can go hand in hand. The connotation of low-carbon city has also changed from the environment subject majoring in reducing carbon emission to a comprehensive subject including society, culture, economy and environment. Low-carbon city has become a macro-system synthesizing low-carbon technology, low-carbon production & consumption mode and mode of operation of low-carbon city. At last it will be amplified to the entire level of ecological city. The promotion of low-carbon city construction has a profound background of times and practical significance. Just as Professor Yu Li from Cardiff University of Great Britain has summed up, at least there are reasons from three aspects for the promotion of low-carbon city construction: firstly, reduce the emission of carbon through the building of ecological cities and return to a living style with the harmonious development between man and the nature; secondly, different countries hope to obtain a leading position in innovation through exploration on ecological city technology, idea and development mode and to lead the construction of sustainable city of the next generation; thirdly, to resolve the main problems in the country and local areas as well as the problem of “global warming”. -

Balanced land use functions (LUFs) can promote sustainable land use and reduces land pressures from limited land resources. In this study, we propose a new conceptual index system using the entropy weight method, regional center of gravity theory, coupling coordination degree model and obstacle factor identification model for LUFs assessment and spatial-temporal analysis. This framework was applied to 17 cities in central China’s Hubei Province using 39 indicators in terms of production–living–ecology analysis during 1996–2016. The result shows that (1) LUFs showed an overall upward trend during the study period, while the way of promotion varied with different dimensions. Production function (PF) experienced a continuous enhancement during the study period. Living function (LF) was similar in this aspect, but showed a faster rising tendency. -
