The invention relates to an urban cellular automaton scene simulation method, a terminal device and a storage medium. The method comprises the following steps of: S100, collecting an ecological environment data of a research area; S200, performing ecological environment evaluation according to the collected ecological environment data, and obtaining an ecological index as an ecological constraintfactor; S300, establishing an ecological constraint based on an ordered weighted average in the urban cellular automaton according to the ecological constraint factor; and S400, establishing a urban cellular automaton model based on a logistic regression according to the ecological constraint, so as to simulate a city space dynamic evolution process. The urban cellular automaton scene simulation method couples an urban model of a binary logistic regression, the ordered weighted average and the cellular automaton, which is beneficial to identify the region with the most contradiction and stressbetween the urban development and the ecological constraints and give a reasonable solution, and is also beneficial to find trade-offs between the development and the protection for urban managementdepartments.

The invention belongs to the field of horticulture, and particularly relates to a method for identifying and evaluating cold resistance of ramie germplasm resources. In order to evaluate the cold resistance of ramie rapidly, accurately and easily, researchers screen multiple indexes such as physiological indexes, ecological indexes and morphological indexes, but it is found in research that most of the indexes have no relationship with plant mortality, and direct evaluation on the cold resistance of the ramie through the indexes is difficult. According to the method for identifying and evaluating the cold resistance of the ramie germplasm resources, operation is easy, evaluation and classification data are stable and reliable, and the defect that ramie germplasm can not be identified accurately under the natural environment is overcome; time limit does not exist, and ramie germplasm cold resistance identification can be conducted from late February to mid October; the evaluation and classification of the cold resistance on the ramie germplasm resources are facilitated, and screening of ramie germplasm which has the cold resistance and selection of ramie varieties which have the cold resistance are facilitated.
