Lake Honghu, in the heartland of Hubei Province, covers a vast but shallow body of water and surrounding marshlands. It is conducive to farmland irrigation, flooding regulation, adjustment of the local climate and self-purification of the water quality. Because of its benign functions, the native ecosystem of the lake is ecologically sound, and the thriving wildlife in its ecosystem makes it a primordial pool of biodiversity. Besides, it is possible to transform it into a national base for environmental education and an R&D center for freshwater organisms, so that it can play a constructive role in heightening the public's awareness of environmental protection.展开更多

The results show that there are 42 species of colored-leaf trees in Lhasa City,belonging to 31 genera and 18 families,of which there are 5,19,and 18 species of spring,autumn,and common colored-leaf trees,accounting for 11.90%,45.24% and 42.86% of total number of the investigated tree species respectively. It is clearly seen that there are too few species of spring colored-leaf trees in the city. There are 19 and 17 species of trees possessing red and yellow leaves,while the leaves of other 6 species of colored-leaf trees are shown in other colors,and the number of their species accounts for 45.24%,40.48% and 14.28% of total number of the investigated tree species respectively. The best ornamental periods of spring,autumn and common colored-leaf trees in Lhasa City average 38.4,41.8 and 251.8 d respectively. Prunus cerasifera Ehrhar f. atropurpurea Rehd.,Ulmus pumila L.,Populus × beijingensis W. Y. Hsu,and Salix alba are applied most frequently in Lhasa City,and their relative frequency is 18.67%,10.29%,9.91% and 8.95% respectively. According to the comprehensive assessment value of their ornamental characteristics,the ornamental characteristics of 15 species of colored-leaf trees in Lhasa City are good or very good,and there is a positive correlation between the comprehensive assessment value and relative frequency. Based on the investigation,the current application situation and problems of colored-leaf trees in Lhasa City were analyzed,and solutions to the problems were proposed.展开更多

This study aims to reevaluate its status and values. Analyzing the causes, limits, advantages, and properties characters of health instruments in CM, it is found that weak fundamental research, incomplete self-awareness, and complicated social factors are the primary causes of debates. A comprehensive analysis showed health instruments in CM have health evaluation benefits to people from a dominant Chinese culture, meet the requirements of cultural background, and bring long-term value to Chinese instrument researches. However, its values and status should be treated differently depending on various subtypes. Although little theoretical and practical evidences proved that patients-reported health instruments in CM should be proposed independently, the doctors- and nurses-reported questionnaires are necessary. With this in mind, the study group proposes the 'Chinese cultural instruments(CCIs)' and 'health-related CCIs'. The latter one aims to evaluate the health status of people in a dominant Chinese culture. The CCIs theory represents Chinese instrument researches on a larger regional and higher level, and resolves the debates on instruments between CM and Western medicine in China. Health instruments in CM bring more scientific and social benefits for Chinese instrument researches. However, it does not include cultural demands, and lacks scientific significance. CCIs have all its virtues, and add solutions to the latter's theory bottleneck and scientific debates, thus bringing increased benefits to clinical assessment in complementary and alternative medicine researches.展开更多
