How do you identify landscape components? What are landscape components?

Landscape components refer to the distribution and composition of substrates, mosaics, corridors, animals, plants, biomass, heat, moisture, air, mineral nutrients, etc. in the environment.

It is the important functional area of the landscape area or the composition point of the scenic spot, such as pavilions, water platforms, sculptures, characteristic water features, xx peaks... and other special attractions.

It refers to the characteristic components such as climate, soil, and vegetation that make up the landscape type.

Plaque: is a non-linear area of the ground surface that is different in appearance from its surroundings. The main causal mechanisms or origins include disturbance, environmental heterogeneity and human planting, which can be divided into several types, such as disturbance plaque, residual plaque, environmental resource plaque and introduced plaque.

Plaques are measured by plaque size, plaque shape, inner edge ratio, number and configuration of plaques.

Corridor: refers to a narrow strip of land that is different from the substrate on both sides, and it can be in the form of isolated strips, such as highways and rivers; It can also be said to be in a transitional continuous distribution with the surrounding substrate, such as some strip logging sites in the process of regeneration. It can also be seen as a linear or ribbon-like plaque, which is also a bridge that connects the plaques.

Length: Plaques with a width of 10-20 or more can be seen as corridors, which play the role of dividing and connecting plaques.

Substrate: It is the type of landscape element with the largest area and the best connectivity in the landscape, and there are three criteria for judging the matrix: 1. Relative area

When one element of the landscape occupies more area than the others, this feature type may be the substrate, which controls the main flow in the landscape. 2. Connectivity: If a certain element in the landscape (usually a linear or ribbon element) is connected relatively well and surrounds all other existing landscape elements, it can be regarded as a substrate.

3. Dynamic control: If an element in the landscape has a greater degree of dynamic control over the landscape than other element types, it can also be regarded as a substrate.

You only need to compare the above three concepts to clearly determine the plaque, corridor and substrate.

In 1986, Professor Forman and Professor Godron jointly published an important monograph "Land-scape Ecology", in which the theoretical model of landscape ecology research was formally proposed for the first time "patch-corridor-substrate", the substrate represents the most important landscape elements of the landscape or region, the patch means the diversity of landscape elements, and the corridor means the connection and protection function between landscape elements. Generally speaking, the substrate is usually the largest landscape component in the landscape system, the patches are the landscape components surrounded by the matrix, and the corridors are usually the relatively narrow landscape patches in the landscape system.

Substrate, the largest area of the landscape is the substrate.

Patches, landscapes surrounded by a matrix are plates.

Corridors, it is corridors that connect the patches.

Look at the definitions of these names and you'll get to know it.

There are not so many rules and regulations, landscape pattern analysis, the key is to analyze the essence of the site!

Sheep blade grid, this pattern is lucky, the water flows eastward, and it will be rich. It's okay to have wood in the name. It is also used as a meridian double bag.

First of all, the easy way to identify organic fertilizers is to blister them with water. After soaking in water, the organic matter and impurities in the organic fertilizer will be stratified, the organic matter usually floats in the upper part, while the impurities such as sediment are precipitated in the lower part, and the organic fertilizer with more precipitation in the lower part is of poor quality.

Secondly, distinguish the advantages and disadvantages by the weight of organic fertilizer. For the same organic fertilizer, high-quality organic fertilizer is generally lighter because it contains more organic matter; Inferior organic fertilizers are generally heavier due to more mixed sediment.

Again, you should also check the pH test strip when purchasing, and it is better to have a pH value of about 7. Soak the organic fertilizer with a small amount of water, dip a small amount of fertilizer solution with pH test paper, and then compare it with the standard color card to determine the pH of the organic fertilizer.
