[Method] The study was conducted in Liangfengya, Shennongjia National Nature Reserve. In the field investigation, six clumps of umbrella bamboo which grow independently were randomly selected and labeled. Rhizome elongation growth parameters, length and diameter of all the ages were measured. The age classes of bamboo rhizome were ascertained by age grade backtracking method. [Result] Field investigation suggested that at seedling phase, rhizome of umbrella bamboo prolonged very quickly under yearly time sequence, following an exponential curve. It indicated that although it was 15 years since the mother population died back, new generation had not been established its stable population yet. [Conclusion] Studying elongation regulation of umbrella bamboo may provide the theory understanding of life cycle of this long lived bamboo species.展开更多

[Method] The relationship between Major Function Oriented Zoning (MFOZ hereafter) and agricultural development is explored with the case of Long'an County in Guangxi. [Result] In the research, agricultural function, featured by composition and diversification, is considered one of territorial function typs, contributed by ecology, land, industries and population. With Long'an as a study case, it can be concluded that the plan of major agriculture-oriented counties is as follows: With guidance of territorial function, the counties should formulate the strategies of major function oriented zones, strive for more social and economic resources for agricultural development, extend agricultural functions, enhance the role of agricultural additional functions, strengthen ecological conservation, improve agricultural productivity and transportation, reinforce exchange of countryside with other regions. In addition, attention should be paid to reconstruction of population and industry pattern for redistribution on the basis of evaluation on bearing capacity of resources and environment. [Conclusion] In future, major agriculture oriented county should coordinate relationship among agriculture, industries, ecology and population with rational distribution of territorial function in county to guarantee stable and sustainable agricultural development.展开更多
