Study On The Management Of The Tianjin Binhai Saline-alkali Afforestation

The Tianjin Binhai New Area's salt clay distribution is broad, the salinity is high,and the vegetation coverage fraction is very low. The newly developed area mustgradually become"the new city which is suitable to live and have the excellentecology surroundings", it is mainly through clay the afforestation, plants the flowerand seed grass on the Binhai salt to enables the built-up district afforestation coveragefraction to achieve 40%. This article has conducted the preliminary study to theTianjin Binhai Saline-alkali land afforestation management, proposed the goal on theregion afforests and should adopt management measure:1. The article has discussed the object management on the region afforests. Afteranalyzing the urban green space system of Tianjin Binhai area, the article chose threepractical significance afforestation object: The community afforests, the path afforestsand the coastal zone afforests, then formulated the corresponding afforested goalseparately, proposed the vegetation selection principle and the planter proportionstructure and so on.2. The article has analyzed the salt alkaloid vegetation's breeding selectivemanagement. After having determined the region afforest goal, the article analyzedthe type and the distribution about the bears salty vegetation, concluded the type andthe quantity of the existing bear salty vegetation on the Tianjin area, rested on thedefinite region afforestation goal, the article analyzed and established the suitable typeand the classification of the bear salty vegetation's structure.3. The article summarized the Saline-alkali soil ameliorate management. Thearticle summarized seven soil ameliorate methods, its significance lay when theselective salty vegetation can not satisfied the area afforestation proportion structureand the vegetation selection principle, and then we could adopt each kind ofSaline-alkali soil ameliorate management in order to satisfy the afforested request.Simultaneously, the article will also analyze the shortcoming of the generalSaline-alkali soil ameliorate and try to improved them.4. The article has radiated about the afforested vegetation's maintenancemanagement. The article analyzed the maintenance management method on thespecial salt alkaloid ground, summarized the afforested management principle, andalso study how to carries on transplants and maintenance after afforesting.
