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
本文把洛塔現存植被分為自然植被與栽培植被兩大類進行研究,通過遙感技術對現存植被按針葉林、闊葉林、密灌、灌叢、草灌、荒草裸巖、農作物植被等類
型進行分佈面積的統計,在此基礎上,以林產品價值、涵養水源價值、保護土壤價值和凈化空氣價值作為估算的主要參考依據,對已成林的針葉林與闊葉林進行森林生態系統的價值估算,得出面積為1388 . 8hm ~ 2的針葉闊葉林的森林生態價值為1836 . 37萬元,參照這一生態價值量,把洛塔植被按常綠落葉林、針葉林、針闊混交林、闊葉林、疏林?灌叢、
矮灌叢、荒草灌叢、經濟作物和糧食作物,以每hm ~ 2的價值量提出了洛塔植被的綜合價值體系。

On the bases of the galaxy evolution theory, we use the therotical chemical evolution model of three zone ( such as halo, thick disk and thin isk ) and multi - phase ( diffuse gas, molecular clouds, stars of both low and high mass, the remnants ). by comparing with the observational constraints, such assurface densities, age - metallicity relation, g - dwarf metallicity distribution in the solar neighbourhood and the correlation between [ a / fe ] and [ fe / h ], supernovae rates, infall rates. the rationality of the model is verified. based on the theory model, we calculate the abundance of neutron capture element

The vegetation types are described of baishanzu national nature reserve in qingyuan county, zhejiang province. the surveyed area covered25thousand hm 2 in which27sample plots with20m 20m each were selected. based on the importance value of plant species, six vegetation types were devided, viz. evergreen broadleaved forest, evergreen and deciduous broadleaved mixed forest, coniferous and broadleaved mixed forest, coniferous forest, mountain dwarf forest, and mountain shrub and herbosa. floristic composition, community structure, and trend of community succession of each vegetation type are described
