Embodiment 1

[0056] Example 1 Construction of Disaster Prevention Harvest Estimated Density Control Chart

[0057] 1 Raw data collection and preliminary processing

[0058] The present invention utilizes the data of the eighth national forest resources inventory in Fujian Province. The first-class survey sample plots in Fujian Province are distributed on the intersection points of the 4×6km grid, and the sample plots are square with an area of ​​667 square meters.

[0059] There are two types of data files for each plot, namely the "sample plot data file" describing the stand characteristics of each plot and the "sample tree data file" describing each sample tree in the plot.

[0060] Sample land data file comprises 75 survey factors, and sample tree data file comprises 11 survey factors, and the factor that the present invention adopts is: dominant tree species, canopy density, stand age and plant number per unit area (N) and tree species (S), Diameter (dbh) and tree (single tree) volum...

Abstract

The invention provides a disaster prevention control method for a man-made Cunninghamia lanceolata forest and relates to the field of forest management. The method comprises the steps of investigating sample plots of the man-made Cunninghamia lanceolata forest to be planned, and carrying out disaster prevention control on the man-made Cunninghamia lanceolata forest by using a pre-created disaster prevention and harvesting estimated density control chart, so as to improve the stability and resistance of standing forests and achieve relatively excellent harvesting and disaster prevention and reduction. According to the method provided by the invention, growing stock harvesting estimation can be carried out on a created cutting and raising scheme, results and operation objectives are estimated comprehensively, the density of the man-made Cunninghamia lanceolata forest is subjected to real-time adjustment, and each development stage of the Cunninghamia lanceolata forest can form reasonable stand density until final clear-cutting harvesting is carried out, so that the condition that the productivity of individual Cunninghamia lanceolata is brought into full play is guaranteed on the premise that the occurrence of disasters is avoided, the space is utilized to the maximum, and relatively excellent operation objectives are achieved.

Description

technical field [0001] The invention relates to the forest management field, in particular to a fir plantation management method for preventing crown fire, snow disaster or wind disaster. Background technique [0002] Chinese fir (Cunninghamia lanceolata) originates in my country and is widely distributed in 16 provinces in the south of my country. It is a fast-growing tree species cultivated in plantations. Chinese fir has been cultivated for more than 1,000 years. Its planting area has reached 9,215,000hm 2 , accounting for 28.53% of my country's forest area. In addition, it is estimated that 25% of commercial timber comes from fir plantations. Therefore, it is an important biological resource in our country. [0003] However, based on climatic factors and improper management models, natural disasters such as windfall and snow disasters commonly exist in Chinese fir plantations, resulting in serious damage to Chinese fir plantations. For example, in 2005, when Typhoon...
