Study On Attribute System Of Quality Assessment For Scenic And Recreational Forest In Beijing

The forest landscape quality rating indicator system establishment's goal describes the forest landscape present situation, forest landscape quality by target form, qualitative or quota expression. The research establishment scenic and recreation forest's quality rating indicator system, may unify the scenic and recreation forest theoretically the evaluation criteria, practices may provide the basis for the scenic and recreation forest management and operation, causes it toward both attractive, and has the good amusement and rest function grove development. This article main findings are as follows;(1) This research take the forest ecology, the forest cultivation study, the forest-esthetics and the psychological physics as the theory instruction, from the tree seed choice, in the single tree landscape, the forest outside the landscape, the forest the landscape four criteria has established the scenic and recreation forest quality rating indicator system, has provided some theory basis for the next scenery amusement and rest forest's construction.(2) This article utilized the analytic hierarchy process to obtain the indicator system various targets weight, obtained the target to the scenery amusement and rest forest quality influence size, thus built, the transformation for the scenic and recreation forest o provide the basisâ‘ In the tree seed choice aspect, the scenery amusement and rest forest builds the transformation choice the tree seed to have ornamental is first, chooses these to have good ornamental, specially observes the flower tree seed; The big tree, the bush, the perennial herb are the vegetative forms which the people like; In order to increase the scenic and recreation forest the attraction, may introduce the exotic species suitably, but must pay attention possibly creates the biological invasion the danger.â‘¡When scenic and recreation forest improvement cutting, should retain the crown complete growth to be good, the bough is straight from end to end, the bark smooth or has the luster trees, cuts down these deadwoods to be serious, because the crown and the neighbouring tree overlap, the bough surface roughness plant disease to cause the bark color unusual standing timber. Moreover speaking of the scenic and recreation forest, to increase Judeich's multiplicity and the beautified function, should retain some shape unusual trees (leaning cross bar, multi-pitchforks wooden, curved bending-wood).â‘¢In forest landscape attention place for under spatial structureï¹¥horizontal intervisibility degree ï¹¥species compositionï¹¥Judeich's densityï¹¥forest landscapeï¹¥bough obviously indication. The people the landscape like the factor to the forest in including: Likes the diaphanous grove; Tree regular or random arrangement, not too likes the tree accumulation the arrangement way; Multi-level vertical structures; Has the good level to be possible the intervisibility distance; The mixed forest, likes the biographical sketch or the belt-shaped conifer and broadleaf even mixed forest; The density is moderate; Under the forest the landscape fills the grass unification to be good; In the grove has the few dead tree but actually wood and does not have the deadwood fallen leaf nearly; Has the big tree, the bough indication is obviously good.â‘£Outside the forest the scenery is paid attention to the place for the landscape mottlingï¹¥seasonal aspect changeï¹¥crown levelï¹¥crown quality of material. The people the landscape like the factor to the forest outside including: The mottling color is rich; The mottling may distinguishing be good, may distinguish obviously; The spot shape shape is consistent with the terrain; The mottling has the good connection; The grove has the seasonal aspect change; Has the height scattered about level crown level; Mix nature crown quality of material...
