Technical Field

Background
The effective prediction of the regional ecological quality annual scenes is a premise and guarantee for reasonably developing and utilizing regional ecological resources. The annual prediction and evaluation work of regional ecological quality depends on the evaluation of regional ecological quality conditions. Currently, the evaluation aiming at the regional ecological quality condition can be divided into a comprehensive evaluation method and an indicator factor evaluation method.
The comprehensive evaluation method is mainly based on methods such as principal component analysis, cluster analysis, distance discrimination, fuzzy mathematical evaluation, grey system evaluation, matter element analysis, hierarchical analysis and the like, a reasonable comprehensive evaluation index system is screened to evaluate the ecological quality condition of the region, but the evaluation mainly refers to the history and the current situation of the ecological quality of the region, and the method has more evaluation indexes selected and has higher difficulty in realizing dynamic annual scene prediction.
For simplicity and ease of operation, a single indicator is often used to indicate the ecological quality status of the area, e.g., a change in net first productivity of vegetation is often used to indicate the ecological quality status of the area. Due to the fact that actual measurement difficulty of the vegetation productivity in a large range of the area is high, estimation is conducted on the basis of remote sensing or meteorological factors. The main problem in estimating the productivity of the vegetation in the area by using remote sensing data and then carrying out related evaluation is that the existing evaluation method needs vegetation indexes to participate in calculation, so that the annual prediction of the vegetation productivity has practical difficulty aiming at the evaluation of the vegetation productivity of a historical time sequence.

In particular, climate production potential refers to the highest biological yield possible per unit area of land when local light, heat, water climate resources are fully and rationally utilized, while other conditions (e.g., soil, nutrients, carbon dioxide, etc.) are optimized. Climate production potential calculations can be made by screening suitable climate production potential models. In this example, the climate production potential of the area to be evaluated is calculated according to the thornhwaite-Memorial model. For regional scale, the change of ecological conditions in a short period is mainly regulated and controlled by the most active meteorological factors. Therefore, it is a promising technical method to effectively predict and evaluate the regional ecological quality new year by using the weather or climate and the prediction information.

In this example, the yield K is the percentage increase and decrease of the climate production potential relative to the average state production potential of the standard climate, and positive values are the yield K and negative values are the yield K. When the standard climate average state production potential is selected, the average value of 30 samples in the last 30 years in history is used as a reference point of the perennial value of the corresponding climate element, and the standard climate average state production potential is updated once in 10 years.

In particular, regional ecological quality is defined as the relative merits of regional climate production potential compared to standard climate mean state production potential. In this embodiment, the regional ecological environment quality may be divided into different levels of quality, and sequentially corresponds to the annual scenes of good and bad ecological quality. For example, the quality of the regional ecological environment is divided into 6 grades of good year, bad year, and step S103 may specifically include:
and step S1031, if K is more than 10, outputting the regional ecological environment quality grade of the region to be evaluated as the youth. And S1032, if K is more than 5 and less than or equal to 10, outputting the regional ecological environment quality grade of the region to be evaluated as a preferred year. And step S1033, if K is more than 0 and less than or equal to 5, outputting that the quality grade of the regional ecological environment of the region to be evaluated is equal to or slightly superior. And S1034, if K is more than or equal to-5 and less than or equal to 0, outputting the regional ecological environment quality grade of the region to be evaluated as being equal to or slightly inferior. And step S1035, if K < -5 is more than or equal to-10, outputting the regional ecological environment quality grade of the region to be evaluated as a bad year. Step S1036, if K < -10, outputting the regional ecological environment quality grade of the region to be evaluated as the bad year.
And step S104, outputting the good and bad ecological quality annual scenes corresponding to the regional ecological environment quality levels according to the preset corresponding relation between the regional ecological environment quality levels and the good and bad ecological quality annual scenes.
In this embodiment, the quality of the regional ecological environment is divided into 6 grades of good year, bad year, and bad year, which respectively correspond to the best year, good year, bad year, and 6 year scenes of ecological quality, and step S104 may specifically include:
and S1041, if the regional ecological environment quality grade of the region to be evaluated is the good year, outputting the good and bad ecological quality annual view of the region to be evaluated as good. Step S1042, if the regional ecological environment quality grade of the region to be evaluated is a preferred year, outputting a preferred ecological quality annual view of the region to be evaluated as preferred.

And step S1044, if the regional ecological environment quality grade of the region to be evaluated is a fair year, outputting a good ecological quality year scene of the region to be evaluated as a fair year. Step S1045, if the regional ecological environment quality grade of the region to be evaluated is a poor year, outputting a good ecological quality annual view of the region to be evaluated as a poor year. And S1046, if the regional ecological environment quality grade of the region to be evaluated is the inferior year, outputting the good and inferior ecological quality annual scene of the region to be evaluated as the inferior.
