Method for evaluating grape climate regionalization in Chinese continental monsoon climate regions

Abstract

The invention discloses a method for evaluating grape climate regionalization in a Chinese continental monsoon climate region. The method comprises the following steps: collecting data, analyzing thedata, establishing a digital elevation model, establishing a climate model and establishing a damp-heat index. Based on the digital elevation model, space calculation combining multivariate linear stepwise regression and residual interpolation is adopted, simulation errors are reduced to a great extent, it is found that the matching degree of a zoning scheme and actual cultivation conditions of all counties is extremely high through comparison with climate zoning results, the important factor of air humidity is added into the zoning scheme, the index of the damp-heat index is provided by referring to the hot index for evaluating the comfort degree of people, and the index quite conforms to the climate characteristics of China.

Description

technical field [0001] The invention relates to the field of zoning indicators, in particular to a method for evaluating the climate zoning of grapes in China's continental monsoon climate zone. Background technique [0002] Grape ecological regional planning is the first step in the development of the grape industry. Selecting suitable climatic conditions for proper planting is the basis for ensuring that the industry does not take detours and develops efficiently and steadily. The grape types cultivated in the world are mainly Vitis viniferaspp. The best ecologically suitable area for Eurasian grapes is the Mediterranean climate type, which is characterized by warm and humid winter and spring, and dry and less rainy summer. World-renowned wine producing regions such as France, Italy, Spain, California, Australia, Chile, South Africa, etc. , are all of this type of climate. The eastern part of my country's main grape producing areas belongs to the continental monsoon climate ...

[0006] Meteorological factors have a comprehensive effect on the human body. Not only high temperature will cause the human body to feel heat, but when the relative air humidity is high, the heat dissipation of the human body will be hindered and the body will also feel heat. Therefore, in areas with high humidity and high temperature, people's body temperature It will be 5-10℃ higher than the actual temperature. Similarly, the high temperature superimposed high humidity environment will also have different degrees of impact and damage on the various physiological activities of vigorously growing plants. The difference is that the plant's tolerance to temperature and humidity The degree is obviously higher than that of humans. Summarizing the critical temperature and air humidity conditions that affect the photosynthetic physiology of grapes and the air humidity conditions that affect the incidence of diseases by the predecessors, the photosynthetic rate of grapes will be significantly reduced at 35°C, and the growth rate will also be significantly reduced. High-temperature grapes are prone to sunburn, and various fungal diseases occur when the air humidity is higher than 80% (Zhai Heng, 2015; He Puchao, 1999; Pang Jian, 2016; Banowetzetal., 2007), according to the calculation formula of the original heat index The temperature and humidity bases are improved to finally obtain an ideal formula suitable for describing the physiological response of grapes in a high-temperature and high-humidity environment. Therefore, the present invention proposes a method for evaluating the climate division of grapes in China's continental monsoon climate region to solve the problem of prior art. problems in
