1402 results about "Habitat" patented technology

In ecology, a habitat is the type of natural environment in which a particular species of organism lives. It is characterized by both physical and biological features. A species' habitat is those places where it can find food, shelter, protection and mates for reproduction.

Habitat friendly, pressure conversion, wind energy extraction

A habitat friendly, pressure conversion, wind energy extraction system is disclosed for safely extracting usable energy from wind. The system includes one or more shrouds or concentrator wings that convert the dynamic pressure of wind into relatively lower static pressure and thereby induces a vacuum that draws wind into a turbine centralized within the shrouds or concentrator wings. As such, the turbine impellor blades may be significantly smaller than the large diameter rotor blades of current popular designs and may be enclosed within the shrouds or concentrator wings that present themselves as highly visible objects and as such are easily avoided by birds in flight. The novel system in particular includes a device and method of airflow regulation than minimizes or prevents the stalling, or the generation of a turbulent flow of wind over or between the shrouds or concentrator wings. This stalling has been shown to occur when airflow is quickly accelerated by force of vacuum and drawn out of the turbine shroud which then mixes with and disturbs the otherwise smooth flow of wind over or between the shrouds or concentrator wings. The system may also include an aerobrake that responds quickly to protect the impellor blades or associated mechanisms from overspeeding or exceeding other design limitations under gusting or violent wind conditions. The system may also include a method of guiding elements of the system to orient appropriately into prevailing winds, and a method to support elements of the system, without unduly impeding the free flow of wind. Other advantages and objects are as well disclosed that increase safety and efficiency, increase installation potential, reduce costs and expenses, and minimize negative environmental impact.

In-situ biological-ecological recovery integrated system for urban river water body

The invention relates to an in-situ biological-ecological recovery integrated system for an urban river water body. The in-situ biological-ecological recovery integrated system is capable of effectively preventing the problems of unqualified fluvial cross section water body and aquatic ecosystem damage and further improving the landscape effect. According to the technical scheme adopted by the invention, the method is as follows: close-to-nature riverside buffer zones are constructed on side banks of a river reach from upstream to downstream; the river reach, at which the close-to-nature riverside buffer zones are positioned, is internally and sequentially provided with a pretreatment unit, a first ecological floating bed unit, a first ecological filtration dam unit, an aquatic plant unit, a second ecological floating bed unit, a second ecological filtration dam unit, a biomembrane-enhanced purification unit including a plug-flow aeration unit, a habitat improvement unit and an aquatic organism functional group construction zone from upstream to downstream. The in-situ biological-ecological recovery integrated system does not need to occupy land area except for a riverway, is stable in treatment effect, does not influence drawing off of floodwater in the riverway, can be used for solving the problems of unqualified fluvial cross section water body and aquatic ecosystem damage and improving the landscape effect, and has great economical and social benefits.

Vegetation configuration method for preventing water and soil loss of mine dump of dry-hot valley

The invention discloses a vegetation configuration method for preventing the water and soil loss of a mine dump of a dry-hot valley. The method comprises the following steps: performing topsoil stripping on the dump; building an intercepting ditch, a drainage ditch and a water collecting tank on a platform of the dump; screening vegetation types, including shrubs, herbs and liana, suitable for growing in the mine dump of the dry-hot valley; performing targeted planting; after the vegetation of the mine dump is planted, enclosing the dump by using a wire mesh or a fence to prevent a slope surface from being destroyed by domestic animals. According to the principles of soil and water conservation and restoration ecology, vegetation species are reasonably combined by aiming at that the habitat of the mine dump of the dry-hot valley is severe and different slope positions have different soil erosion intensity and water conditions, so that a reliable technical path is provided for recovering the vegetation in a mining region as quickly as possible. Moreover, the vegetation configuration method for preventing the water and soil loss of the mine dump of the dry-hot valley has the characteristics of high operability and high comprehensive benefit.

Regional scale plant disease and insect pest prediction method based on multi-source information

ActiveCN103034910AFine information outputForecastingInsect pestPlant disease
The invention relates to the technical fields of remote sensing and spatial data analysis treatment and agronomy, and discloses a regional scale plant disease and insect pest prediction method based on multi-source information. The regional scale plant disease and insect pest prediction method based on the multi-source information comprehensively applies the satellite remote sensing data reflecting vegetation physiological status and the regional scale meteorological data reflecting the meteorological conditions to the prediction of plant diseases and insect pests, thereby overcoming the defect that a traditional disease and insect pest prediction model does not take the influence on the occurrence rate of the plant diseases and insect pests from the vegetation growth status habitat parameter differences among fields into account. The regional scale disease and insect pest prediction method based on the multi-source information takes the vegetation stress conditions and the habitat information of different planting fields into the model input, outputs the occurrence rate of the plant diseases and insect pests in different planting areas through a standard model under a certain field condition, and outputs more accurate information about the predication of the plant diseases and insect pests.

The invention discloses a remote-sensing crop disease identification method based on time phase and spectrum information and a habitat condition. Multi-time-phase visible light-near infrared and thermal-infrared remote sensing images in a study area within a monitoring period are obtained and pretreatment is carried out on the images; with the remote sensing images after pretreatment, planting information of target crops is extracted by combining a certain kind of classification algorithm; and according to the visible light-near infrared and thermal-infrared remote sensing images, habitat information of disease monitoring is obtained, a disease area and a disease type of the target crops in the study area are determined by combining the time phase information of the target crops and the obtained habitat information, and severity of the disease is determined by using the spectrum information based on the determined disease area and disease type. According to the technical scheme, the remote sensing diagnosis precision of the crop disease can be improved effectively; and a reverse identification problem of remote sensing crop disease monitoring can be solved to a certain extent.
