Description
Technical field
The present invention relates to ecological protection technical field more particularly to a kind of Ecological Control line demarcation methods of intelligent interactive
And device.
Background technology
Ecological Control line refers to the integrality, science and continuity that the ecosystem is safeguarded for support area ecological safety,
The chaotic expansive for containing urban land, under the premise of respecting reasonable environmental carrying capacity and natural ecosystems, according to related method
Rule, law, calmodulin binding domain CaM own actual situation and the ecological environmental protection boundary line that divides.Ecological Control line is in region sustainable development
Extremely critical effect is played in exhibition, eco-environmental management and protection of resources etc..But Ecological Control line is still fallen within newly
Emerging things delimit standard, demarcation method and management system etc. so far all without clearly unified regulation.
Existing Ecological Control line demarcation method can be mainly divided into two major classes type.
First kind method, it is relatively conventional in the ecosystem environment management work of reality, i.e., by combining the routine spaces GIS point
The technologies such as analysis method, ecological suitability analysis and artificial comprehensive drawing delimited.It will forbid open in survey region first
It sends out the existing program results such as area, ecologically fragile areas, ecological sensitive areas and carries out Spatial Overlap Analysis；Then Ecological Suitability point is carried out
Analysis, and the high place of suitability value is also included within the scope of Ecological Control line, until meeting area requirements；Finally by artificial
Figure spot is processed, rejects tiny independent patch etc. one by one.For example, Geneletti and van Duren utilize GIS
Spatial analysis, multiple target and multicriteria evaluation method have divided Italian Martino ecological preservation area, they firstly evaluate research area
Then the Ecological Suitability of each homogeneous unit carries out conservation of nature Division according to the sequence of suitability numerical value.
Tulloch et al. combination GIS and multicriteria evaluation method realize the division of U.S. Hunter regional farming land protection zone, Ta Mentong
The correlative factors such as soil regime, block area and the neighborhood land use of evaluation studies area cropland are crossed, are determined respectively with this
The protection priority of cropland.Bender et al. is explained by comprehensive 3S technologies and ecological field field exploring, to Shenzhen roc
The ecosystem, marine resources, species resource and its distribution in new district know the real situation in detail, and have divided ecology based on this
Protective wire hierarchy plan.Swallow, which is kept, wide et al. makes the eco-environment resource situation in Jiangsu Province using remotely-sensed data and GIS technology
Assessment, and the stringent management and control area of level-one and two level ecological protection management and control area delimited across the entire province based on this, per level-one
It is subdivided into 15 class ecological protection line regions.
Second class method is then to automatically generate Ecological Control line scheme using various Multiobjective Intelligent optimization algorithms merely,
The division of Ecological Control line is namely considered as land use planar space optimization problem to handle.It is also needed first to studying area
Domain carries out ecological suitability analysis, then weighs search automatically using intelligent algorithm and show that the Ecological Control line of near-optimization delimited
Scheme.For example, Li et al. people carries out the Ecological Control line Research on partition of Guangzhou using ant group algorithm, they are to conventional ant group algorithm
Neighborhood search strategy and information update mechanism be partly improved, make its be particularly suited for solve planar space optimization ask
Topic, the experimental results showed that the effect of optimization of new method than conventional GIS spacial analytical methods than get well.Chen Ming brightness et al. then proposes to adopt
The Ecological Control line scheme that Dongguan City, Guangdong Province is automatically generated with discrete particle cluster algorithm, with similar, the Ta Menye of a upper research
Conventional particle group algorithm be partly improved for use in processing planar space optimization problem, research finds that new algorithm can take
Obtain best effect of optimization.And Shao et al. has divided the natural, ecological of Hainan Province Sanya using emerging artificial bee colony algorithm
Protection zone, and comparative analysis has been carried out to the effect of optimization of various common intelligent algorithms.Liu et al. people then utilizes artificial immune system
The Basic Farmland Conservation Zones that model carries out Guangzhou divide, and comparing result finds the effect of optimization ratio GIS spatial analysis of the model
Method will be got well.
But there are still apparent defects for above-mentioned existing Ecological Control line demarcation method.
The shortcomings that first kind method, is to divide and evaluation criterion has stronger subjectivity, and process very complicated, needs
A large amount of manpower and materials time resources are expended, the degree of automation is insufficient.In addition, there is no consider protection zone spatial framework for this method
Compactness, mark off come Ecological Control line scheme typically more disperse and be crushed, be not easy to actual monitoring and management, have
When be difficult to efficiently play the role of preserving the ecological environment.For the eco-environment resource management in reality, if one can be taken
The protection area scheme of relative compact can not only alleviate the negative effect that urban sprawl is brought, and be conducive to migrating for species, maintain
The integrity and stability of the ecosystem, and carry out investigation and management monitoring violating the regulations etc. convenient for protection zone staff.
Although and the second class method it is contemplated that survey region Ecological Suitability value and Ecological Control line pattern it is tight
It gathers degree, but does not account for existing all kinds of ecological environmental protection program results (such as all kinds of nature reserve areas, basic farmland are protected
Protect area, main functionality section planning), physical geography boundary and present status of land utilization etc., institute's splitting scheme cannot rationally and effectively with
Mutually linking and coordinate, it is possible to there is " more rule " conflict phenomenon.Planning a multitude of names related with ecological protection suffers from each
From spatial dimension, function and management system, therefore delimit Ecological Control line and be just faced with and " strive " soil with other Correlative plans
Predicament.
