Carrying capacity of water environment in public tourism resources based on matter-element model

When water environmental carrying capacity of public resource tourist attraction is studied, the two action subjects of tourists and local residents should be discussed, and comprehensive consideration must be given to the influence of these two on water environment. On the basis of water resource carrying capacity and water quality carrying capacity, water environmental carrying capacity index of public resource tourist attraction was constructed, the model for the water environmental carrying capacity of public resource tourist attraction was established on the basis of matter-element model and analytical hierarchy process. By applying this method, water environmental carrying capacity situation of a certain public resource tourist attraction can be gained, moreover, situations about several aspects of water environmental carrying capacity can be evaluated.

A Preliminary Study of the Training of Drawing Skills for Civil Engineering Majors in Higher Vocational Colleges Under the “1+X” System

Architectural engineering drawing skills are one of the important standards of talent ability that construction enterprises pay attention to.Under the“1+X”system,as a pilot college of“1+X”in higher vocational education,and according to the standards of“Vocational Skill Level Certificate in Architectural Engineering Drawing,”a channel to improve students’core working skills is explored through the implementation of the teaching reform.

General review of National Digital Library development in the National Library of China

As an important part of National Digital Library(NDL),the National Digital Library Project(NDLP),which was launched in 2005,has attracted wide attention of the society in general.This paper introduces the general situation of the project from the following aspects,namely,the characteristics,objectives and contents.It also expounds on the basic ideas and the overall structure of the project and gives an introduction to the design of its basic platform,its application platform,its business management system and its standardization control system.In this paper,the digital resources construction and service delivery of the National Library of China(NLC)are introduced to cover both its present operation as well as those in conjunction with the opening of its new library building during its second-phase of library development.Finally,the most important and difficult point in the construction of the National Digital Library Project is analyzed from the following four perspectives:1)The long-term preservation of digital resources;2)the construction of knowledge organization system;3)the organic integration of the digital library and the traditional library;and 4)the risk of project management and system integration.

Wastewater reclamation and reuse in China:Opportunities and challenges

The growing water stress both in terms of water scarcity and quality deterioration promotes the development of reclaimed water as a new water resource use. This paper reviewed wastewater reuse practices in China, and the opportunities and challenges of expanding reclaimed water use were analyzed. Rapid urbanization with the increasing of water demand and wastewater discharge provides an opportunity for wastewater reuse. The vast amount of wastewater discharge and low reclaimed water production mean that wastewater reuse still has a great potential in China. Many environmental and economic benefits and successful reclamation technologies also provide opportunities for wastewater reuse. In addition, the overall strategy in China is also encouraging for wastewater reuse. In the beginning stage of wastewater reclamation and reuse, there are many significant challenges to expand wastewater reuse in China including slow pace in adopting urban wastewater reuse programs, the establishment of integrated water resources management framework and guidelines for wastewater reuse programs, incoherent water quality requirements, the limited commercial development of reclaimed water and the strengthening of public awareness and cooperation among stakeholders.
