Ethnobotanical surveys were carried out in four ecological zones （I, II, III ＆ IV） involving a sample of 433 persons from 29 ethnic groups. Semi-structured interview, field observation, group discussions were used to collect data. Food shortage periods were defined using the agricultural calendar of main crops in three ecological zones （I, II, ＆ III）. One hundred and one EWFS belonging to 84 genera and 39 families were inventoried. The three main types of use of the EWFS were direct consumption, condiments and medicines. Twenty among the 101 EWFS recorded were highly consumed during food shortage periods with respectively 15 EWFS in ecological I, 14 in zone 1I and 12 in ecological zone III. All edible fruits consumed during food shortage periods were fresh fruits with abundant pulp. Six fruit species were sold to bring income to local households. These species were those which benefit from conservation measures through their husbandry in agroforestry systems.展开更多

Wake up the national ideology of reading. In this context of the times, the Library undertakes the important task of advancing the national reading, libraries should continue to strengthen self-construction, and work together with other institutions and government, strangthaning our universal reading mechanism and developing it into a mature career.展开更多

This paper firstly conducts the comparative analysis between traditional and ecological industry as well as traditional and modem industrial engineering, and in- dicates that eco-industrial engineering is an inevitable choice for sustainable development of modem industrial engineering; Then, based on industrial ecology, environmental economics and sustain- able development theory, the connotation and definition of eco- industrial engineering are proposed, and the theoretical and practi- cal development of the concepts of eco-industrial engineering are further investigated. Furthermore, the research subject, research content, academic system architecture and evaluation methods of eco-industrial engineering are discussed. Finally, combining the current scientific and technological development, we put forward the important scientific value and practical significance of con- structing eco-industrial engineering for the utilization of these concepts.展开更多
