Moso Bamboo forest is an important forest ecosystem. Although there is a sharp decline in today’s global forest area, the Moso Bamboo forest area expands at a rate of about 3% per year, suggesting that Moso Bamboo forest is an ever increasing carbon sinks. China has highest diverity of Moso Bamboo resources in the world, which accounts for about 1/3 of the world’s bamboo species and bamboo forest area. Moso bamboo is the main type of bamboo forest. National research on the forest resources shows that China has an area of 386.83 million hm2 Moso bamboo, accounting for 71.89% of the bamboo area. In the 21st century, bamboo forest area of the rapidly expanding and the rapid progress of science and technology. Therefore, this study chose Moso Bamboo as an observation object..Moso bamboo is one of the main bamboo species in South China whose planting area is very wide in the south, and also an important economic crop. So it has an important economic and ecological meaning of reseashing on Moso Bamboo. This study observe the continuous course from bamboo shoots to grown bamboo of Moso Bamboo in the state-owned forest farm of Yixing city. Through analysis can we get the following results:Moso Bamboo’s growth is usually divided inyo three stages——in the first stage, from the beginning to the 24th day, Moso bamboo grew slowly; in the second stage, from the 24th day to 52th day, Moso Bamboo grew dramatically; in the third stage, Moso Bamboo had grown up basically and had a slow growth. The state-owned forest farm with a electronic tree mensuration instrument and MINI type rangefinder in Yixing City, Using 3D angle method and photogrammetry of Moso Bamboo height, diameter at breast height data were observed, via electronic tree mensuration instrumen post processing system, bamboo monolithic photogrammetry software and precise angle measuring bamboo software are analyzed by experimental data. Finally, the MATLAB software for photogrammetry software solutions for count data models were fitted, handheld electronic measuring tree gun data was evaluated and the Hsinchu moso bamboo high with time varying models for:H= 14.72/(1+1616* e0.04165x1/-0.2027) or H=14.64/(1+e7.577-0.2113x), Hsinchu bamboo diameter changes with time model:D= 2.489* x1.373e-0.1828x. And calculate the number of experimental form of this kind of Moso bamboo is 0.2175 plots and Moso bamboo divided into single tree average peripheral volume 0.03017m3, finally obtained outside the bamboo yuan a volume is: V=-0.006105+0.0004164D^2. Finally when Moso Bamboo stand density in 245 strains/ha, the area of bamboo forest is divided into volume reached maximum 110.966/ha, at this time of the bamboo forest diameter at breast height (DBH) for 11.11cm. Through the study of mao bamboo’s grow model and the optimal density, we can improve the growting capacity、economic benefits and ecological benefits of mao bamboo, providing a fine theoretical basis and reference for the local bamboo cultivation management, which has an important meaning for the sustainable operation of Moso Bamboo.
