| Country human habitat forest as a key component of new countryside construction is more and more extensively concerned, when China is currently exploring and experimenting socialist new countryside construction. taking Fujian province as a case, This paper systematicly studyed the country human habitat forest,which is significance not only to new countryside construction but also to modern forestry in Fujian, while other parts of our country can demonstration and reference.This paper used stratified sampling method, analysised the courtyard forest, road forest, waterside forest, geomantic forest and esplanade forest in Fujian country. Researched the plant composition characteristics of country human habitat forest in different types and positions. and carryed out a survey with country human habitat forest and villagers will. At the same time, this paper also constructioned the quality evaluation with country human habitat forest in Fujian and layout optimization model. taking the mountainous type, hill type, flat type and coastal type as typical case. The main results as follows:1,The plants composition is very rich in country courtyard forest in Fujian province, including 86 families,186 generas and 245 species, Dominated byPalmae, Moraceae, Rosaceae, Oleaceae,Magnoliaceae,Poaceae, Leguminosae, Euphorbiaceae, Liliaceae, Araceae, Rutaceae.①The plant species and numbers shows:arbor>herbage>shrub>vine, distribution shows:coastal type>flat type>hill type>mountainous type, South>East>West>North.②The dominant plants is mainly composed of ornamental and fruit plants, the application of high frequency plants are Osmanthus fragrans, Dimocarpus longgana Lour, Mangifera indica Linn, Ficus microcarpa, Amygdalus persica Linn, Diospyros kaki Linn, Pyrus sorotina, Trachycarpus fortunei, Eriobotrya japonica, Podocarpus macrophyllus, Camellia japoica, Bougainvillea spectabilis Willd, Psidium guajava, Cycas revoluta Thunb, Chaenomeles sinensis Koehne, Murraya psniculata an so on.③The plant composition diversity shows:Patrick index:arbor>herbage> shrub>vine;simpson index and shannon-wiener index:arbor>shrub> herbage>vine; pielou index:shrub>arbor>herbage>vine.④The plant similarity index:arbor> shrub>herbage>vine, thereinto, flat type and coastal type, flat type and hill type, East and South, West and North in which arbor is high similarity.⑤The plant health status is excellent, thereinto, the proportion of health plants, fair plants and poor plants are 5.64%,89.72%,4.64%.⑥The courtyard forest is dominated by native plants, the exotic plants is only 16.17%, thereinto,the highest proportion of exotic plants is herbage, followed by arbor, while shrub and vine are relatively lower.⑦The number of new plants is rich, the new plants composed mainly by arbor and herbage are dominated by ornamental, edible, expensive.2,The plants composition is richer on country road forest in Fujian province, including 41 families,64 generas and 79 species, Dominated by Palmae, Lauraceae, Sapindaceae, Rosaceae, Moraceae, Oleaceae, Magnoliaceae, Euphorbiaceae, Cupressaceae.①The distribution of road forest is mainly by mainline,followed by pathway, while the village roads are relatively seldom.the characteristic is mainly by unilateral distribution, while bilateral distribution is seldom,the structure is mainly by whole roads,while the scatter distribution is seldom,the distribution length is mainly by less than 50 meters, followed by more than 200 meters, while the length between 50 and 200 is seldom.②The dominant plants is mainly composed of ornamental arbor, the main applied plants are Schima superba, Phoebe zhennan, Michelia figo, Elaeocarpus sylvestris, Sabina chinensis, Liquidambar formosana Hance, Michelia chapensis, Lagerstroemia indica, Dimocarpus longgana Lour, Ficus microcarpa, Dalbergia odorifera, Populus euramevicana, Cinnamomum camphora, Cinnamomum japonicum Sieb, Ficus benjamina Linn and so on.③The plant health status is poor, the porportion of unhealthy plants is 35.57%.④The species and numbers of new plants are rich, thereinto,the number proportion of new plants is 52.3%.the main new plants are Phoebe zhennan, Michelia figo, Elaeocarpus sylvestris,Dalbergia odorifera,Populus canadensis Moench, Cinnamomum camphora, Melia azedaeach,Michelia chapensis, Murray a psniculata, Sabina chinensis, Ficus microcarpa and so on.3,The plants composition is relatively smaller on country waterside forest in Fujian province, including 30 families,42 generas and 48 species, Dominated bySalicaceae, Lauraceae, Ulmaceae, Gramineae, Hamamelidaceae, Juglandaceae, Rosaceae, Sapindaceae. ①The distribution of waterside forest is mainly by rivers,followed by rills, while the ponds are relatively seldom.the characteristic is mainly by unilateral and bilateral distribution, while around distribution is seldom,The number proportion of entire and scatter distribution is similar, the distribution length is mainly by less than 50 meters, followed by more than 100 meters, while the length between 50 and 100 is seldom.②The dominant plants is mainly composed of ornamental and Fruit plants, the main applied plants are Dimocarpus longgana Lour, Phyllostachys pubescens, Dendrocalamopsis oldhami, Celtis sinesis Pers, iquidambar formosana Hance, Pterocarya stenoptera, Cinnamomum camphora, Salix babylonica, Fraxinus mandshurica Rupr, Phragmites australis, thereinto, the waterside forest of western Fujian is better.③The plant health status is relatively better, thereinto, the proportion of health plants, fair plants and poor plants are 15.82%,75.24%,8.94%.4,The plants composition is relatively richer with country geomantic forest in Fujian province, including 35 families,55 generas and 69 species, Dominated by Lauraceae, Moraceae, Fagaceae, Hamamelidaceae, Gramineae, Rosaceae, Sapindaceae, Theaceae, Taxodiaceae, Anacardiaceae.①The distribution of geomantic forest is mainly by single and sheet, the district focus on village gob, temple, housesides, tomb, mountainsides, around village, watersides and others.The number and pattern of distribution are affected by local culture in Fujian.②The main function of geomantic forest is still the geomantic and superstition at this stage.at the same time,the recreation is becoming the main function of geomantic forest.③The protection status of geomantic forests are better, only 19.62% of geomantic forests are damaging or degenerating.④The plant health status is relatively better, thereinto, the proportion of health plants, fair plants and poor plants are 23.13%,72.89%,3.98%.5,The composition of country esplanade forest are more different, thereinto, non-park esplanade forest including underside tree and pleasance have an important role,The plants composition is relatively smaller with country esplanade forest in Fujian province, including 18families,20 generas and 24 species, Dominated by Moraceae, Sapindaceae, Lauraceae, Oleaceae, Cupressaceae, Hamamelidaceae.①The esplanade forest of coastal type and flat type,east and south are better constructed.②The construction of esplanade forest is lag,52.27% of villages have no esplanade, only 47.73% of villages have esplanade,thereinto,63.16% of villages are mainly by underside tree.③The dominant plants is mainly composed of ornamental plants.④The plant health status is relatively better, thereinto, the proportion of health plants, fair plants and poor plants are 11.61%,82.78%,5.56%.6,The result of characteristics comparison of country human habitat forest shows that:①The plants composition of courtyard forest is richer, followed by road forest and geomantic forest, while waterside forest and esplanade forest is relatively poorer.②The plants of geomantic forest and waterside forest is bigger, the plants of road forest is smaller, while courtyard forest and esplanade forest have the two distribution patterns.③The plant health status of geomantic forest and courtyard forest is relatively better, followed by waterside forest and esplanade forest, while the plant health status of road forest is poorer.7,The country courtyard forest is poor construction in Fujian province,only 17.62% of courtyards have the courtyard forest,The main constraints of no virescence are no money and no place, from the overall demand of villagers,the most urgent things are strengthening the human habitat forest on road sides and around village. From various types of the demands of villagers, villagers hope that courtyard plant healthy and beautiful plants, roads are appropriate green, watersides strengthen green, and esplanade build pleasance.8,The quality evaluation method of country human habitat forest in Fujian province is scientific, simple, rapid and accurate,and also can better reflect the status of country human habitat forest. The result of researching case shows that:①The construction of coastal type is better, followed by flat type and mountainous type,while the construction of hill type is poorer.②The construction of country road forest and waterside forest is relatively lag, The forest network density index is lower.9,The country human habitat forest has great potential for development in Fujian province.①The village development potential shows:hill type>coastal type>flat type >mountainous type, we should first strengthen hill type construction in future,followed by coastal type and flat type,while the mountainous type is close to saturation currently.②The index development potential shows:forest structure>forest cover>forest Network density,this shows that current pattern of village has problems, particularly in the construction of road forest and waterside forest, The important aspect of socialist new countryside construction is to strengthen scientific regulation and layout on existing country human habitat forest.
