The Sunan 5 City Forest Resource Status, Dynamic And Countermeasures Research

Forests, as the major component of the terrestrial ecological system, are the most perfectresource library, water storage, carbon storage and energy library in nature. They shouldermulti-mission of ecological construction, forest carbon sinks and the supply of forestryproducts. They are the important material foundation for human survival and development, aswell as the subjects of improving the ecological environment, maintaining ecological balance,and constructing ecological civilization.In this study, the main contents are forest management inventory of five municipalities insouthern Jiangsu. Investigation is all of the forests, trees and forest land in the fivemunicipalities. The content includes the area and ownership of all kinds of forest lands, thevolume of all kinds of forests and trees, forest ecological function, forest health, forestcoverage rate, woody plant coverage rate, and the establishment of forest resourceinformation management system.The findings are as follows: In2007a, forest land area in southern Jiangsu is434241.15hm~2, rate of forest cover is13.26%, woody plant coverage rate is16.06%; rate offorest cover is lower than the provincial average; forests dominated by plantation take up87.54%of the forest area. In various age groups, the young-middle-aged forest area takes up80.11%; non-commercial forest area is190662.76hm~2, taking up43.91%of total forest landarea. Forest ecological functions generally are good, in which the good and moderate gradetakes up91.21%of total non-commercial forest area; forest health own excellentcharacteristics, better than the Jiangsu province, in forested land area, the healthy area is288290.07hm~2, taking up91.38%of forested land area; the unhealthy area is1000.73hm~2,only taking up0.32%of forested land area.Studying on the related data of forest management inventory through two periods (1987aand2007a), the findings are as follows: forest land area, forest volume, forest coverage rateshowed continued growth in the southern region20years. the development and utilization offorest is no longer the one-sided pursuit of economic efficiency, but more emphasis on theecological and social benefits. However, the forest category of the forest resources insouthern Jiangsu remains unreasonable. In various age groups, the young-middle-aged forestis in large proportion. Forest quality is not high status. Total amount of per capita forestresources is still low. Forest carbon sinks capacity is not strong. Compared with the carryingcapacity of the population, resources, environment, the forest resources in southern Jiangsustill cannot meet the needs of the regional economic and social development.On this basis, the paper proposes five-point countermeasures and recommendations ofsustainable development of forest resources in southern Jiangsu: first, to fully use suitableland for forest, to strengthen the target assessment, and increase afforestation efforts toenhance the resources and environment carrying capacity; second, to improve compensationstandards of non-commercial forest, and gradually improve the ecological system; third, tostrengthen forest management, and improve quality and efficiency of forest resources; fourth,to establish woodland classification protection, and implement woodland classificationprotection and management; fifth, to promote forest-property reform, and stimulateenthusiasm and initiative of tree growers.
