Start from the soil properties in accordance with the theories and methods of business in recent natural Liangshui Nature Reserve Xiaoxing'anling Korean pine forest in four different operation types and four different management measures, according to the degree of close to natural, artificial Korean pine forest as the object of study, its forest litters reserves, soil organic matter content, soil physical properties, soil water holding capacity, soil chemical properties and soil microbial characteristics of the system. The results show that: the operating type of forest soil bulk density 0.74g/cm ~ 3 ~ 1.08g/cm ~ 3, significant differences among forest types, as follows: birch Korean pine mixed forest I the Korean pine Artificial Chunlin, birch, red pine mixed forest Ⅱ, the original Korean pine forest. Higher than Korean pine artificial Chunlin, total soil porosity original Korean pine forest soil saturated water is as follows: the original Korean pine forest, the birch Korean pine mixed forest Ⅱ, of Pinus koreansis Chunlin, birch Korean pine mixed forest Ⅰ, soil capillary water holding capacity and field capacity is as follows: The original Korean pine forests, birch Korean pine mixed forest I the Korean pine Artificial Chunlin, birch Korean pine mixed forest II, significant differences among forest types; primitive Korean pine forest of the full amount of soil organic matter content and nutrient elements and two species of birch Korean pine mixed forest were higher than of Pinus koreansis Chunlin. The full amount of the nutrient elements, available K content, followed by birch Korean pine mixed forest in the highest, the original Korean pine forest, Korean pine artificial Chunlin minimum, significant differences between the different forest types; available phosphorus content to the original Korean pine forest in the highest, birch Korean pine mixed forest times , the lowest of Pinus koreansis Chunlin; primitive Korean pine forests and birch Korean pine mixed forest of the total microbial population are higher than the Korean pine artificial Chunlin, the number of bacteria and fungi to birch Korean pine mixed forest for the highest number of actinomycetes to the original Korean pine forest is the highest. Korean pine plantation operating measures the litter reserves order: control> uniform translucent> In addition to filling stay Joe> Joe stay irrigation> full light, full of light, in addition to Joe to stay irrigation understory undecomposed layer share of litter material the larger the proportion of total reserves, control, uniform light transmission, and in addition to filling stay Cholin under semi-decomposition of litter layer share the total reserves; 0.71g/cm ~ 3 ~ 1.08g/cm 3 soil bulk density, in order to In addition to filling stay Cholin sub-minimum. Total soil porosity order: In addition to Joe stay irrigation, uniform light transmission, control, full of light, in addition to filling stay Joe. Soil saturated water, capillary water holding capacity and field capacity are in addition to irrigation, leaving Joe> Light> uniform transmittance> CK> irrigation in addition to Joe to stay, but different management measures on soil water holding capacity is not significant; soil organic matter and highest stand of nutrient elements in full uniform translucent. Different due to management measures and indicators of soil nutrients, soil available nutrient content of seasonal variation showed a different variation; soil available nutrient content are uniform translucent highest, in full light and in addition to Joe to stay irrigation minimum, the same soil in different forest was significantly different (P <0.05); consistent trend of seasonal variation of bacteria and fungi, showed a single peak curve maximum occurs in July and August; the actinomyces season dynamic in the stand and in addition to all-optical Joe to stay the shrubbery is divided into first and then decreased, and in addition to filling stay Cholin sub-divided into uniform translucent forest increased and then decreased. Number of bacteria: In addition to filling stay Joe, uniform light transmission, control, light, in addition to the number of fungi: Joe stay irrigation control, in addition to filling stay Joe, in addition to Joe to stay irrigation, uniform light transmission, all-optical, actinomycetes bacteria count is as follows: In addition to filling stay Joe, uniform light transmission, in addition to Joe stay irrigation, all-optical control. Different business types with different operating measures Korean pine forest soil properties under study are confirmed to improve the species composition and stand structure conducive to improving the quality of Korean pine forest woodland. The results provide a theoretical basis for Korean pine forest operators.
