Forest Resource Inventory Technology New Issued The Prescribed Application And Analysis

"The Main Technique Provision for Forest Planning and Designing" plays an importantroll in standardizing the programming and investigating management units, protecting forestresources and developing multi-function performances of the forest resources. The government ispaying more attention to and spending more money on the ecosystem, and environmentconstruction, thus, the forestry guiding thought has changed from: "making lasting use of timber"to "the three greatest performances developing together while the ecosystem performance takingprecedence" With the widely application of new technique and methods, the previous TechniqueProvision is not suitable for the new changes and requests.As a county in Zhejiang, Chun'an, which has the biggest area for forestry, is selected to makeexperiments. Its purpose is to study the scientific approach, function and maneuverability of thelatest technique Provision. It plays an important roll in establishing and completing practicaldetailed regulations for the second survey of forest resources, summarizing the experience of thesurvey according to the newly revised Technique Provision, improving the efficiency and accuracyand promoting the scientific management of the forest resources. It is also the important item thatneeds to be solved urgently at present.This special subject is studied by combining the nature deciding with ration deciding. First, itis studied and analyzed how the previous Technique Provision is not suitable for the new changesand requests of the new forestry. We do research on the method to survey the forest resources indeveloped countries and the effect that the reform of local forest proprietorship has upon theTechnician Provision. Then we analyze the background in which the new Technician Provision isrevised. We also carry out a concrete analysis on the new Technician Provision according to thesurvey of the forest resources in China.The previous Technique Provision is not suitable for the new changes and requests of theforestry at the moment. The reasons are as follows:1. The woodland classification does not agree with the Forest Law or its implementregulations.2. Restricted to the technique at that time, no requests are put forward to the application ofnew technique and methods.3. The rules for survey the "multi-layer-and-different-age forest," especially the"choose-to-cut forest" are not suitable.4. It is not very close to the management of forests.Chun'an is the first county in Zhejing that use the GRS and the calculator technique, combinesampling control with subcompartment inquisition to check its forest, wood and woodlandresources, study and establish the geographic information system which agrees with the collectiveforest management characteristics, according to the new revised Technique Provision and requestsfor managing the forest established by the National Forestry Bureau, 2003. focus on the need forecosystem construction. It has got rich information. This is different from those previous surveywhich focused on the resource figures. It has made a breakthrough. It is applied and analyzed asfollows:1. It standardizes how to classify the forests. The newly revised Provision Standardize theecological public welfare forest, focusing on the subcompartment inquisition. And at the sametime, all the counties and cities in Zhejiang have classified their forests according to the new classification standards and make it stable. Forest resources management survey should make fulluse of the results of the classification to agree with the previous results as much as possible.Chun'an classified 138171.5hm~2 of ecological public welfare forest, 38.5%of all the forestsin the county, The wood stored adds up to 5210276m~3, 47.19% of the amount stored in all theforests. The Ecological Public welfare forest are divided into nation- class; province-class,city-class and county-class according to its proprietorship and special protection, point protectionand general protection according to its importance. The land structure involves woodland,condense wood and bush wood. These have been recognized as the results of classifying theecological public welfare forest of the nation class and province class. The forestry ecologiccompensation has been settled. The local government has established plans concerning thepreservation and management according to the results.2. It explored the contents of the ecological survey. According to the new Technique Provision,experiments were done to study the community structure and the nature degree. The communitystructure is restricted to the arbors. The result is: the arbor area in all over the county's ecologicalpublic welfare forest adds up to 120386.1hm~2and 7079.8hm~2 of it, 5.9% of the whole area of theecological public welfare forests has the complete community structure. The area of thecomplicated community structure is 103973.3hm~2, 86.4% of the whole area. Simple communitystructure is 9333.0hm~2, 7.7%. The classification of the nature degree, according to the ecologicalconcepts, focuses on natural arbors and natural shrubs. Its result is: the area of arbors and shrubs is199228.4hm~2. Community of DegreeⅠ, which means being original or hardly influenced byhuman beings, is 16890.2hm~2, 8.5% of the whole area of the natural forests. Community ofDegreeⅡ, which means being obviously affected by humans or the secondary community in themiddle or late course of the differentiations, is 168442.1hm~2, 84.5%. Community of DegreeⅢ,which means being greatly affected by humans, nearly destroyed or hard to go back to the latecourse of the differentiation, is 13896.1hm~2, 7.0%.The studies of the new Technique Provision plays an important roll in establishing andcompleting the practical regulations for forest resources management survey, looking for theexperience as improving the scientific management of forest resources. It is hoped that my articlecan provide the policy makes with some basic and play an active roll in managing the forests.
