The Returning Farmland To Forest's Main Ecology Effect And The Value Research In The Hilly Area Of West Part In Henan Province

The forest is the main ecosystem land, has the watersource self-control, the conservation of water and soil, the windproofsolid sand, the solid carbon oxygen manufacture, improves the soil,the purification environment, the reduced disaster, protection biodiversity and so on the various function. The development forestecology benefit value appraisal research, to enhances social public to theforest important understanding the utilizationeconomical method protection forest ecosystem, the establishment greenGDP calculation system, constructs the structure and aspect and so onfunction good forest ecology System all has the extremely vitalsignificance.This article in the synthesis correlation research foundation, discusses take the utility value with ecology Das Kapitalas the theory basis, uses indirect gauging device which substitutesand simulates, takes back from agriculture also the forest benefit monitor network near for 3 year localizations observed data accordingto Henan Province, took back from agriculture the self-control watersource, the solid earth to the Henan Province Luoning County which also, the improvement soil, the solid carbon and oxygen made manufacture, the improvement microclimate, reduces the waterdrought, the forest traveling, the protection of wild animals and soon eight ecology effects and the value has carried on the appraisal.Appraised the result is: Through calculates Luoning County to takeback from agriculture also the forest microclimate benefit value from2002 to 2004 is 25.08 million Yuan, the forest self-control watersource value, if according to the running water market pricecomputation, the Henan Province running water average price is 0.5Yuan/cubic meter, calculates Luoning County according to this price totake back from agriculture also the minute self-control watersource value is 8.922181 million Yuan. Also may use after thehydraulic engineering adjustment water source price to calculate. Theproject sailor standard, the national reservoir 1 m3storage capacity the construction cost (0 67 Yuan) to substitute, thenLuoning County took back from agriculture also the forest microclimatebenefit value from 2002 to 2004 is 25.08 million Yuan, the solidcarbon produced the oxygen value respectively be the average everyyear 84.852 million Yuan and 152.629 million Yuan. Took back fromagriculture the findings to Henan Province which also the forestproject ecology effect and the value appraised to establish the forestecology benefit to compensate the mechanism to provide the reference.The forest ecology benefit value appraisal research is an item ofcomplex systems engineering, at present although had the basic theoryand the method, but also insufficiently mature and unified, theappraisal result difference quite is also big, but also needs to dothe further thorough research.
