Summary of the knowledge points of the Geography test for the first year of high school 1

Environmental Carrying Capacity

p>

①Definition: Number of people to feed (survival)

②Influencing factors: resources (main factors, determined by the most scarce resources, barrel effect), economy, etc.

< p> ③Characteristics: uncertainty and relative certainty. The world is 10 billion, China is 1.6 billion

Reasonable population capacity, definition: the number of well-fed people (development)

Influencing factors:

①Natural environment: positive Correlation (the actual population indirectly reflects the size of the reasonable population capacity)

② Regional openness: positive correlation (Japan, the Netherlands, and Belgium use other countries’ resources)

③ National natural resources: positive Related

④Quality of life and consumption level: negative correlation

⑤Level of scientific and technological development: When the resources developed are greater than the resources needed: positive correlation; when the resources developed are less than the resources needed Required resources: Negative correlation

⑥The gap between rich and poor: Negative correlation

1. Population growth

1. The main factors affecting population growth: productivity level, medical and health conditions and education level affect the mortality and birth rate of the population, which in turn affect the growth pattern of the population. In addition, policies, social welfare, natural disasters, etc. will also affect population growth.

2. Population growth model (population reproduction model): high-low-high (developing countries with lower levels), three-low (developed countries), transition from "high-low-high" to "three-low" (lower-level high developing countries).

3. World population growth: Africa has the lowest natural population growth rate in Europe; Asia has the largest net increase in population.

4. Population problem - population growth is too fast: population pressure is high - population control (China implements family planning)

Population growth is too slow: population aging - encourage childbirth , accept immigrants (China relies on developing productivity)

2. Population migration

1. The main reasons for population migration: economic (from backward areas to developed areas), politics (political persecution, war) , state-organized population migration), social culture (religious persecution, ethnic discrimination), ecological environment, and other factors (family wealth and marriage, seeking relatives and friends, escaping discrimination).

2. The significance (effect) of population migration

(1) Benefits: ① Strengthen ethnic unity and promote ethnic integration ② Strengthen cultural exchanges ③ Reduce population pressure in the place of relocation ④ Relocation provides cheap labor.

(2) Disadvantages: ① Causes brain drain in the place of relocation ② Increases the difficulty of social management in the place of relocation

3. Population distribution and population capacity

1. Population and environmental carrying capacity: the number of people that a certain region can support in a certain period of time.

Reasonable population capacity: the number of people that can be sustained. The reasonable population capacity is smaller than the population carrying capacity.

2. Factors affecting environmental population capacity (environmental carrying capacity): resource status, productivity level, openness and consumption level.

Meteorological disasters

Main meteorological disasters: refer to heavy rains, floods, droughts, typhoons, cold waves, and strong winds Disasters directly caused by factors such as sand and dust, heavy (dense) fog, high and low temperatures.

Typhoon disaster prevention measures: Strengthen typhoon monitoring, issue typhoon forecasts or warnings in a timely manner, and organize everyone to do a good job in fighting typhoons in a timely manner.

Heavy rain and flood prevention measures: Use meteorological satellites to monitor heavy rain and floods to improve forecast accuracy and reduce flood losses.

Engineering measures: build dams, regulate rivers; build reservoirs; build flood diversion areas (or flood detention, flood storage areas, etc.). Non-engineering measures: land management in floodplain areas; establishing a flood early warning system; formulating emergency evacuation plans and countermeasures for residents; implementing flood protection insurance, etc.

Drought prevention measures:

① Implement an agricultural structure that combines agriculture, forestry and animal husbandry to improve the ecological environment in arid areas;

② Plant drought-tolerant crops; < /p>

③Carry out farmland water conservancy infrastructure, build protective forests, improve farming systems, etc.

Cold wave defense measures: Publish accurate cold wave news or warnings in advance to remind relevant departments to prepare for cold weather.
