Study On Forest Fire Loss Assessment

The forest fire is that is burnt in the forest out of hand. Fire has a great destructiveness to forest, endangering extremely dark, quite serious even economic losses that cause. It not merely burns a large amount of forest reserves, destroys natural environment in the forest zone and ecological balance, and influences the development of national economy, threatens the security of the people's lives and properties seriously.It is an important part in the modern woods fire management that the loss of forest fire is assessed. In the foundation of synthesizing the studying the current situation of forest fire both at home and abroad, and according to the ecological benefit and social benefit and economic benefit that forest has, the paper divides the loss of forest fire into the economic loss, ecological environment loss and social benefit loss, then subdivides on the foundation. The economic loss is divided into for the direct economic loss and indirect economic loss. Direct economic loss includes standing trees resource loss, economic forest loss, bamboo grove loss, fixed assets loss, expense of putting out the fire, current assets loss, resident's property loss, etc. The direct economic loss is the direct consequence on function of forest fire, but the serious indirect consequence still exists in the forest fire, The indirect consequence is more serious compared with direct consequence sometimes. Indirect economic loss is which loss might not demonstrate at once but through influence other follow-up economic worth to decrease lose. Indirect economic loss includes state revenues loss, stopping and reducing of product loss, loss causing by atmosphere pollution, travel trade loss, watch trees loss, settling victims loss etc. The loss of ecological environment is divided into the resource loss of animal and plant, the loss of preserving water, the loss of prevent flood benefit, the loss of conserving water and soil benefit, the loss causing by microorganism death and soil physics and chemistry natures changing, the loss or forest absorbing carbon dioxide benefit, the loss of forest purifying atmosphere benefit, the loss or forest suppressing sand blown by the wind, the loss causing by carbon releasing by fire, and other ecological loss etc. On the basis of this classification, and combining the study of forest resource asset assessment, assessment studying, economics etc, the paper puts forward assessment method for the direct economic loss and corresponding appraisal method for other loss.Standing tree resource loss is loss of timber value of living standing tree and withered standing tree which forest fire cause artificial woods everything can be used for produced, Life and other uses. It can be calculated by comparing the value in front of and behind calamity. The value of disaster-stricken forest is calculated respectively by dividing into the same age woods and different age woods according to different structure and different from management style. The value in front of the calamity of the same age woods is calculated by different method according to management type and age group. Young age forest can use the method of reset cost and historical cost change; middle age and near mature forests use the method of current value of income ; mature and after mature forests use the method of current value of timber. The value behind forest fire of different age forest is calculated adopting to the method of current value of income by divided into the different age forest which cut selectively direct and some years after cut selectively because of management style and particularity of growth course. The operator's treatment ways are differentbecause the extent of damage to forest is different, and the calculation of remaining value of disaster-stricken woods is different. If the fire cause destructive damage to forest, the forest is replanted after the fire, then the remaining value is the value of the remaining timber; if fire does not cause destructive damage to forest, the forest is remained to...
