| In this research, different types of broad-leaved mixed forest of bamboo in Chishui Village, Chishui town, Zhangping City, Fujian Province was taken as the study objects, and broad-leaved mixed forest stands of bamboo, bamboo productivity, forest soil fertility, the hydrological effects woodlands has been systematically studied. Researched stands can be divided into A, B, C, D, E ,which are respectively for 10 bamboo , 9 bamboo with 1 broad-leaved, 8 bamboo with 2 broad-leaved , 7 Bamboo with 3 broad-leaved, 6bamboo with 4 broad-leaved. The results of the study as follows:1 In the five types of mixed forest, the condition of stand growth, Utilization Ratio of stand space, microclimate of forest, effect of controlling diseases and pests, stand biomass, and the amount of forest litter in type C and D is better, the mean diameter at breast height of bamboo forest, height, and volume are all higher in type C, D than in type A. The bamboo forest productivity was large , and had rational structure, per unit area of the total biomass of trees and dry wood biomass higher, with a high volume of litter , The bamboo forest in our efforts to improve the ecological environment, maintain and enhance soil fertility, conducive to regulating temperature and moisture, and can effectively control diseases and pests.2 The mean diameter at breast height, mean height, and stand volume of bamboo in type B, C, D, E were all higher than the type A., the density, evenness, uniform and ILA were all higher than pure forest., Various types of mixed type in the above-mentioned indicators to type C, D are better; According to the various types of Rhizome length, rhizome diameter, and the numbers of rhizome stage, Rhizome growth better in type C, D, E ,0-40 cm total rhizome length, respectively, compared with an increase of 6.25%, 9.06% and 10%; as to the growth condition of rhizome bud, strong bud were mainly distributed in the strong-age scourges, significantly reduced in the old-age scourges and the young-age scourges. From the different types, strong bud in type C, D were much more than others, up to 19, and 11 for the type A, type C, D made advantage for the growth of P pubescence. come to the conclusion that type C, D can make full use of solar energy, improve the ecological quality of bamboo and enhance the system's feedback mechanism of energy and material circulation, with higher productivity and significant economic benefits.3 The difference was significant compared with the different types of bamboo forest on the soil structure destruction rate, The results revealed that Type C (broad-leaved trees account for 15% -25%)had the lowest soil structure destroy rate, type A had the highest soil structure destroy rate. The rate of soil structure deterioration of different types of stands on was followed by: A> E> D> B> C; among all types, the soil moisture regime in type C, D, E were better; the penetrate the soil properties was the best in type C, the penetrating speed and rate, respectively ,was 11.00, 4.54mm/min; the most nutrient status of the soil was relatively higher in type C, lower in type A, the ability of fertilization of the pure bamboo forests was weaker than the bamboo mixed with broad-leaved forest, may be due to the litter fall of the larger proportion of broad-leaved forest was more, and break down to the forest after the release of the more nutrient-induced.4 The biomass and moisture capacity of the tree layer in different types of bamboo and broadleaved mixed forest stands were increasing with the proportion of broad-leaved tree, stands in various types of planting, the canopy water-interception capacities was increased with the increasing of the proportion of broad-leaved tree, both of them were higher in type E, respectively, up to 72.848 t·hm-2, 2 mm; from different types of bamboo and broad-leaved mixed forest, The standing crop and moisture capacity of the litter was increased with the increasing of the proportion of broad-leaved tree, the best was type D, rise respectively by 12.123 t·hm-2, 1.526mm, the soil water storage capacity of different types was various, the strongest was type D, was up to 392.6mm, the weakest was type A, in order to 348.4mm; different types of mixed forest, as a whole, the highest of the moisture capacity was type D, reaching 397.165mm, the lowest was type A, had 350.62mm; from the various types of crown interception, litter and water retention properties of forest land water storage effects such as hydrological studies, along with the increase in the proportion of broad-leaved trees, the Indicators were basically enhanced. With more broad-leaved tree, tree stand litter layer and the higher the standing crop that can retain more rainfall, effectively reduced the surface run-off, showing a strong ability to conserve water sources.5 The result on stands of bamboo forest, bamboo productivity, soil fertility of the gross bamboo, bamboo forests and the effects of hydrological of the different types mixed forest show that all indexes of the type C, D were better than others, and 8 bamboo with 2 broad-leaved and 7 bamboo with 3 broad-leaved were the most reasonable stand structure of bamboo.
