The model was calibrated and validated against the historical monitored data from 2005 to 2009. The streamflow was estimated by downscaling HadCM3 outputs to the daily mean temperature and precipitation series, derived for three 30-year time slices, 2020s, 2050s and 2080s. Results suggest that daily mean temperature increases with a changing rate of 0.435~C per decade, and precipitation decreases with a changing rate of 0.761 mm per decade. Compared with other seasons, the precipitation in summer shows significant downward trend, while a significant upward trend in autumn. The annual streamflow demonstrates a general down-ward trend with a decreasing rate of 0.405 m^3/s per decade. The streamflow shows significant downward and upward trends in summer and in autumn, respectively. The decreasing rate of streamflow in summer reaches 1.97 m^3/s per decade, which contributes primarily to the decrease of streamflow. The results of this work would be of great benifit to the design of economic and social development planning in the study area.展开更多

This article combined with the background, based on the birth rate, mortality indicators as well as the corresponding changes in the age structure, demographic trends predict the future based on the current form of the economy analysis the population of 60 years since the founding of New China .China＇ s population control based on the complexity of the future still need to take tight family planning policy, change the mechanism of population control, optimize population structure, improve population quality.展开更多

Tourism development planning should use land planning, regional planning and territorial planning to be related to the overall urban planning coordination, it shall comply with the relevant provisions of the national infrastructure plan. Tourism development planning should be coordinated with scenic spots, nature reserves, cultural and religious sites, cultural relic＇ s protection units and other professional planning. National Tourism Bureau is responsible for organizing the preparation of the national tourism development plan, the development of regional tourism planning across provincial development planning and national priorities identified tourist routes, and tourist areas; local tourism bureau is responsible for organizing the preparation of the administrative region tourism development plan. According to the relevant provisions of the National Tourism Administration Tourism Planning and Design Qualification management, tourism development plan is announced for the preparation of qualification units. Tourism Development Plan prepares for the economic and social development which should be market prospects, resources, environmental factors to conduct a thorough investigation to obtain accurate basic data, it starts from the market demand attention ecological environment and cultural heritage protection and continuation of the positive use of advanced planning methods and techniques.展开更多

This means we can not only consider our current short-term interests, but also give our future generations a healthy and sustainable environment to further develop the natural and cultural environment. In those environmental conditions, our future generations can have the same quality of life as us forever, keep ecological and sustainable development of the world, and even be able to have a better quality of life than ever before. In sustainable urban development, first of all, it is to be in accordance with the laws of nature to have a cooperative and friendly attitude to treat the environment. In this rational way of working, we must respectfully treat human nature, it is a huge sustainable ecosystems. We can either learn a lot of knowledge from nature＇ s perfect eco-cycle system, but also it can be used in future planning and design.展开更多

It assumes： （i） the perception of their regional rootedness works beneficially for enhancing sustainability; （ii） current progress in place＇s conceptualization helps in the quest for sustainability, since the core factors of the concept deal precisely with the relationships between people and environment. The paper works both with the perception of existing, as invented places, analysing the perception they stimulate. Real places are seen as socially constructed; invented places, as economically promoted. Selection of empirical regional cases is based on their： perception （real and invented places）; scale （urban and ex-urban）; management （public or private）. In the area of Architecture-Urbanism, place is a created environmental form, imbued with symbolic significance to its users. In the present shift of paradigms from modernism to postmodernism, the discipline evolves towards a more thorough concern with the philosophical implications of places on phenomenological grounds. Also, the making and marketing of new places become increasingly accepted as influential tools to foster prosperity and well-being, by means of the economic development attributed to the creation of places. The concerted private and public management of the region＇s places and the restrained design they presently employ are providing grounds for an affluent development, showing a wise use of the regional resources.

Presumably, the concept of place, positioned as it is at the very interface of physical, social, economic and behavioural disciplines, seems to provide a likely means for tackling the challenges for a sustained regional development planning.展开更多
