| Artificial forest is an important forest ecosystem with magnitude function and effect in wood production, environment protection and sightseeing construction. This item summarize the main technical measures of artificial forest management in Thousand-isle Lake, study changing dynamic and shaping reason of artificial forest management, analyze influence of artificial forest growing from different stand terra,vegetation and construction method with standard place investigation method through 266 standard place investigation in Cuninhamia lanceolata and Cupressus funebris artificial forest in Thousand-isle Lake managed by Xinanjiang Development Corporation (Head Office), Chunan County. Anatomy existent problem of artificial forest, combine with social economic development and modern forest construction requirement, accordingly put forward sustainable management and control development idea and countermeasure of artificial forest in Thousand-isle. Conclusion is listed as follows:1,The company has a quite large scale with 500387m3 stand wood accumulation 4876.60hm2 Cuninhamia lanceolata artificial forest area,153279m3 stand wood accumulation 1440.93hm2 Cupressus funebris artificial forest area. The area and accumulation rate of Cuninhamia lanceolata forest and commonweal forest is 3:7,the area and accumulation rate of Cupressus funebris forest and commonweal forest is 2:8. Near and mature forest is not higher than middle age forest from accumulation per area indicating great scatter cutting intension or more scatter cutting high layer.2,Request of Cuninhamia lanceolata pure forest for stand terra is higher than mixed forest. Deep soil layer must be selected for construction Cuninhamia lanceolata pure forest with few vegetation underneath forest in favor of Cuninhamia lanceolata growing. Productivity of Cuninhamia lanceolata pure forest is distinctly higher than. Productivity of Cupressus funebris pure forest is almost as same as mixed forest. Request of Cupressus funebris for stand terra is inferior to mixed forest with extensive adaptability especially in tiny alkali or lime rock mountain land, purple sandstone where Cuninhamia lanceolata is unsuitable to grow while Cupressus funebris get well insead.3,Annual average tallness growth, pathway growthand accumulation growth of Cuninhamia lanceolata is distinctly higher than Cupressus funebris.Notable level square margin analysis account for higher productivity of Cuninhamia lanceolata while Cupressus funebris is suitable for constructing mixed forest. Annual output of Cupressus funebris pure forest is 83.57%higher than Cupressus funebris pure forest while annual output of Cupressus funebris mixed forest is 2.82% higher than Cupressus funebris mixed forest through comparison from investigation annual average accumulation and annual output calculated from current market value.4,According to the request of righ land for righ tree and classify management, it must be reinforced to cultivate Cuninhamia lanceolata and Cupressus funebris artificial forest. Control the intensity of cutting, avoid over cutting large path wood, repair gloomy and low Cuninhamia lanceolata and Cupressus funebris artificial forest with ecological and sightseeing cultivation, bring its promised benefit into play. On the basis of integrated consideration of local social economy development, market demand and environment requirement, reasonable distribution of forest types such as artificial forest and natural forest, conifer and broad-leaf tree, timber forest, economic forest and protective forest etc, forest distribution variety and sightseeing structure complexity, boost up productivity of artificial forest, sustainably develop artificial forest base on economy and environment service, adopt many objectives management measure such as expanding near natural forest, improving artificial forest management mode, artificial forest sustainable management authentication. |
