ジャーナル フリーIn the first reports was discussed a reconnaissance method of vegetation survey for the diagnostic study of succession of the slope vegetation on expressways. In that case study were found many types of communities on various successional stages.
This time the author plan to ellaborate on a quadrate method for the judgement of successional stages of these many types grass slope vegetation.
He made a case study on Meishin expressway, Tomei expressway, and Chuo expressway. Selection of stands for sampling was done for each typical communities. Size of sampling area is about 4-25 m2, where is a enough area for the sampling plot of grassland and scrub communities.
Data were recorded according to Braun-Blanquet method. The number of data was 226 plots. The analysis of the data for the diagnosis of succession was made as follows.
1. The data were classified into 8 communities (Meishin), 6 (Tomei), and 5 (Chuo). The floristic composition in each roads were compared.
2. The comparison of life-form spectra of each roads and each communities was done.
3. The number of degree of succession was calculated for each roads and each communities.
After these comparison, the results of diagnosis is: Meishin (13 years after construction) is the most progressive stages of succession, next is Tomei (8 years), and Chuo (4 years) is the last.
The sere was presumed after the results of floristic composition, life-form spectra, degree of succession, and index of similarities of each communities. The author presumed 4 sere, 2 were orthosere and 2 were plagiosere. Pueraria lobata and Robinia pseudo-Acacia made plagiosere, which do not progress normally to the climax but stagnate in their stages.抄録全体を表示PDF形式でダウンロード (1606K) -

The direct inducement of enforcing the First Park Act is the Message of Mayor Kingsland sended to the municipal assembly, but there are many faults in the city, such as shortage and deteriorate of openspaces, because of rapid growth of urban area. At that time these are peculiar rural cemeteries in each great cities and their design had been applicated the technique of English landscape gardening, besides numbers of city dwellers visited these cemeteries almost cevery week. Both A. J. Downing and W. C. Bryant cleverly discerned those state of things and developed a intense campaigne by means of journalism. Then they've been had a considerable definite plan and idea on location, scale and design of the ground and Olmsted not only expressed his idea on composition of the park aligned himself with theirs, but lively applied his concepts on rural scenery in the center of the city.抄録全体を表示PDF形式でダウンロード (1194K) -
