Population Ecologic Structure Of Dendrocalamus Tsiangii In Karst Physiognomy

This text fastens the population ecologic structure and main biology characteristic of Dendrocalamus tsiangii in Karst physiognomy were studied preliminarily on three aspects of clone small stub and population and consortive group. The result has indicated that Dendrocalamus tsiangii has more stanza number, the stanza is longer, the bamboo wall is thin, doing the form is full, stem living creature quantity specific weight big etc. benefit in the characteristics that thin bamboo strip use. The characters of bamboo density, diameter grade, bamboo height, etc of different consortive groups were determined to analyze the traits of structure types, rationality and habitat, jamming relation and biology characteristic through selecting clone population under different habitat and disturb conditions. Results showed that the growth of the bamboo in hidden slope excelled that in sunny slope; half shading excelled whole sunlight. The consortive group I> II> III> IV should be stable and rational for population ( I,II, III denoted 1,2,3 age of bamboo and IV denoted above 4 age of bamboo) It was showed that it was important to adopt scientific and effective measures, regulate and optimize the cutting amount of Dendrocalamus tsiangii in different ages and strengthen wood tending management. This text makes use of to provide the foundation for the reasonable management of its science according to.
