Results showed soil sampled from the granite parent material had the highest organic matter (43.11 g·kg-1) and available sulfur (38.73 mg·kg-1); however, it had the lowest pH (4.72), available calcium (Ca,5.22 mg·kg-1), and available zinc (Zn,1.65 mg·kg-1). Soil sampled from the phyllite parent material had the highest available phosphorus (P,7.29 mg·kg-1), iron (Fe,31.24 mg·kg-1), and manganese (Mn,67.49 mg·kg-1). Available nutrient elements in C. cathayensis leaves for all soils were in the order: nitrogen (N)Capotassium(K)MgPMnFeZn. Additionally, leaves growing on soil developed from phyllite parent material had the highest available N, Ca, Mg, and Zn, but the lowest available P and Fe. The correlation analysis was also significant for soil pH, soil organic matter, andavailable nutrients. Correlations for N, K, Ca, Mg, and Fe content in leaves as well as content of soil nutrient element were also significant.","PeriodicalId":17498,"journal":{"name":"Journal of the Zhejiang Forestry College","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78612257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to select the optimum farmland shelterbelt type by determining the optimal shelter forest porosity. After choosing the main shelter forest models（Taxodium ascendens forest，mixed Metasequoia glyptostroboides（water fir）-Cryptomeria fortunei forest，M. glyptostroboides forest，Populus spp. （poplar） forest，and C. fortunei forest） and surveying the community structure，rice yield and 1 000-grain weight were determined for each shelter forest. Results showed that at different distances within the same sample plot，forest protection significantly improved rice yield and 1 000-grain weight；leaf area index also improved. Among the different models，yield increase was in the order T. ascendens＞the mixed forest of M. glyptostroboides and C. fortunei＞M. glyptostroboides＞Populus spp.＞C. fortunei. The range of shelter forest porosity was 0.31 - 0.39，and the most effective protective distance was 5H（fivefold height of the tree）－10H. In addition，the mixed forest was better than the monotypic forest with the mixed forest of M. glyptostroboides and C. fortunei being the optimal shelterbelt model. ［Ch，3 fig. 3 tab. 21 ref.］","PeriodicalId":17498,"journal":{"name":"Journal of the Zhejiang Forestry College","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88463908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However，scarce information is available about the effect of P deficiency on the growth of Carya cathayensis. To study root morphology，leaf photosynthesis characteristics，leaf acid phosphatase，and root secreted acid phosphatase of Carya cathayensis seedlings，a hydroponic culture experiment with treatments of sufficient P（0.1 mmolL－1） or deficient P（0.02 mmolL－1） was conducted. Results showed that compared to sufficient P，the low P treatment significantly decreased（P＜0.05） plant dry weight，plant P concentration，plant P accumulation，root length，root surface area，root volume leaf photosynthetic rate，and stomatal conductance； however，there were no significant differences for intercellular CO2 concentration. Additionally，the low P treatment significantly increased （P＜0.05） leaf acid phosphatase （by 135%） and root secreted acid phosphatase （by 159%）. Thus，the low P treatments with decreases in leaf photosynthetic rate and stomatal conductance，but no differences for intercellular CO2 concentration，showed that leaf photosynthetic rate was not due to stomatal limitation. Also，for C. cathayensis an increase in acid phosphatase activity induced by a P deficiency could be an adaptive mechanism to low P stress.［Ch，4 fig. 1 tab. 28 ref.］","PeriodicalId":17498,"journal":{"name":"Journal of the Zhejiang Forestry College","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89605873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that a mixed evergreen and deciduous broadleaf forest with an area of 66.5% and perimeter of 50.7% of the total research area was dominant. Phyllostachys pubescens forest，Cunninghamia lanceolata forest and Camellia sinensis plantation comprised 25.7% of the total area and 37.9% of the perimeter. In Xiaokeng，many small patches with a relatively fine grain structure dominated the forest landscape element. The area，perimeter，and number of patches of different forest landscape element were very uneven；the distribution trend of perimeter of different forest landscape element is similar to that of area，while the distribution of the number of patches has no obvious regularity，and the order of the numbers of patches，area，perimeter is very different； the patch shape of forest landscape elements is relatively simple. Patch characteristics indicated that the degree of fragmentation for the natural broadleaf forest was lower than for artificial landscapes of Phyllostachys pubescens，Cunninghamia lanceolata，and Camellia sinensis. Therefore，to maintain sustainable development in the region，and especially to enhance protection for the broadleaf forest matrix，intense human activity and tourism should be reduced. ［Ch，6 tab. 20 ref.］","PeriodicalId":17498,"journal":{"name":"Journal of the Zhejiang Forestry College","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78398355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also，in the mixed forest of masson pine and broadleaf trees，diversity of regeneration layer and shrub layer decreased，in the Japanese black pine forest diversity of the regeneration layer increased，other forest stands changed little，and diversity of the herb layer decreased. After natural restoration，diversity of vegetation types exhibited little similarity.
