Study On Planning And Construction Of Coastal Shelter Forest System In Shandong Province

From the promoting of coastal shelter forest system construction on the facts,including natural calamity defense, environmental protection and sustainabledevelopment of social economy, and basing on the development process of thatcoastal shelter forest, natural calamity, natural conditions, as well as mainachievements had made in coastal areas of Shandong, effects of coastal shelter forestafforestation on environment were evaluated comprehensively, and main problems ofcoastal shelter forest construction were revealed as well, according to foreign basictheories and main study achievements on coastal shelter forest, the text advancedguiding ideologies, essential principles, construction aims and composition, studies oneight important constructions, five construction models and six countermeasures wereemphasized.The circumlittoral shelter forest system is divided into two stages.Expect(2006-2010 years) a construction target ago for: The engineering area forestoverlays a rate to attain above 28.4ï¼…, basic woodland reaches mark rate 75.3ï¼…, basicconstruct into circumlittoral comprehensive shelter forest system. Expect(2011-2015years) a construction target behind for: The engineering area forest overlays a rate toattain above 31.0ï¼…, basic woodland reaches mark rate 100ï¼…and build up layerdiverse, the function be complete, the performance give attention to both ofcomprehensive shelter forest system.The circumlittoral shelter forest system constructs 8 greatly main contents:Circumlittoral basic woodland construction, inshore shelter forest construction,alongside the sea pool wetly protects and recovers, nature reserve area construction,farmland woodland net construction, the city country be green to turn beautification,low effect wood reformation, forest management, science and technology prop up andscience and technology experiment demonstration area to construct(Rongchengcircumlittoral basic woodland take demonstration area, Shouguang circumlittoralwetly protection and instauration demonstrate area, Rizhao circumlittoral the forestmanagement of the shelter forest system demonstration area) etc..Circumlittoral shelter forest construction the forestation install a way: Accordingto the principle of "establish to defend because of harm, proper because of groundsystem", install a wood to grow to grow with tree, become level structure of take theform(piece form) or irregular allocation and tree to infuse grass, tree to infuse orinfuse grass etc. multilayers of perpendicular structure. Perpendicular structure shouldwith sparseness deeply structure or well ventilated structure is lord, take towardsprotecting fruit tree, economically woodland plantation for lord of shelter forest, adoptclose structure. According to sign a ground of condition and protection functionrequest, choose to mix with broad-leaved tree to hand over with the conifer, the deepnature tree grows to mix with shallow nature tree kind to hand over and the male tree grows and bears a shady tree a kind to mix to hand over and the solid nitrogen treegrow and the not-solid nitrogen tree kind mix to hand over and tall tree and bush mixto hand over etc. Can also reserve a natural renewal tree to grow to combine togetherwith artificial forestation, become to mix to hand over a wood.Circumlittoral shelter forest construction forestation the mode can be divided intothe following 5 kinds:Basic woodland constructs mode: artificial forestation mode of mire quality coastbasic woodland, artificial forestation mode of the sand quality coast basic woodland,artificial forestation mode of the rock quality coast basic woodland, basic woodlandseal mountain(pool) to teach wood's mode.The shelter forest constructs mode: The mountainous country mound shelter forestseals mountain to teach wood's mode, the soil improvement of the salt land a wood toafforest mode, alongside the sea sandy beach to defend breeze a solid sand wood toafforest mode, the water and soil conservation of the mountainous country mound awood to afforest mode.Farmland woodland net constructs mode: The salt such soil area farmlandwoodland net constructs mode, farmland in the sandstorm region woodland net toconstruct mode, ex-plain farmland woodland net to construct mode.The low effect wood reforms mode, city country green turn integral whole to turnconstruction modeThrough study on construction and planning of coastal shelter forest system inShandong province, we described the blueprint of coastal shelter forest system in thefuture, besides, by enforcing visible measures, green ecological defense would bebuilt in coastal areas of Shandong, meanwhile, the coastal shelter forest system withvarious forest and tree species, various structure, various function and according toforest belt to act backbone, maintaining land ecological security and protectingbiology diversity, constructing good human habitat environment that go well withnature, to make contribution to achieving the aim that building ecology province.
