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

Based on an analysis of the history and present status of the farmland - pastoral ecotone in the northern part of china, a new point of view was proposed in this paper for the construction of eco - environmental systems, namely, the industrial structure has to be modified so as to make a functional integration between different parts of the whole system : to give priority to a combination between cultivated grassland and in - shed feeding of domestic animals, and at the same time, to employ a new model of animal husbandry so that the degradated natural grassland can be recovered ; to develop a new type of processing industry for agricultural and forestal products so as to create a pluralistic enterprise structure ; to make a better use of water resources by taking advantages of the abundant resources of energy and minerals, and to restrain the expansion of industries of high environmental cost ; to employ techniques of integration management and restoration ecology, and to speed up the process of woodland and grassland recovery ; to make a thorough plan for arrangements of hills, waters, roads, farmlands, forests and pastures in order to gain an integration at landscape level
