In this paper, two major types, the natural vegetation and crop vegetation in luota are studied. we can gain the different distributive area by remote sensing technology, in accordance with conifer forest, broadleaf forest, thick shrub forest, shrub forest, herbs shrub forest, herbs naked rock and crop vegetation. the valuation of the output of standing trees, water conserbancy, soil conserbation to control erosion and purify the air is the main basis which is used to value the functions of the forest ecosystem of the conifer forest and broadleaf forest of luotathe result reveal that the total ecological function value of the forest which area is 1388. 8 hm2 is estimated up to 18. 36 million yuan per annum. the synthetic valuation system of luota vegetation is put forward by the valuation of per hm2 in evergreen - deciduous forest, conifer forest, conifer and broadleaf forest, broadleaf forest, scatteredtree - shrub forest, coppice - shrub forest, herbs shrub forest, econamic crop and cereal crops. the plant resources is valued according to the ornamental and green plant. lumber trees and medical plant. ornamental plant includes hosta plantaginea. lilium brownii van viridulum, spiraea cantomiensis and so on. lumber tuees includes zzzelkova schneideriana, emmenopterys henryi, catalpa fargesii and so on
