How to treat the scope and boundary of natural geographical environment

How to make the range of natural geographical environment and the range of boundary natural geographical environment can be divided according to the main characteristics of the environment, including single type environment and comprehensive type environment. A single type of environment can be divided into climate, water, vegetation, soil and so on. The boundary can be determined according to various physical and chemical indexes. For example, the atmosphere can be divided into troposphere, stratosphere, middle layer, warm layer and escape layer according to temperature changes, and the division standards are different, and the range is quite different. Comprehensive division is called natural division, which is divided according to the comprehensive differences of various factors. For example, China can be divided into three parts: the east, the middle and the west, which are divided according to climate, landforms and ecosystem types, and its borders are usually served by large mountains and rivers. Due to the gradual change of the natural environment, the boundary between the above two environments is usually blurred. For example, the Qinling Mountains, which divide the north and south of China, are tens of kilometers wide, so the scope and boundaries of natural geographical environment usually have macro and meso characteristics, and it is impossible to be very accurate in a small scale.

How to deal with the relationship between man and natural geographical environment, protect development, and pay attention to the diversity, rational utilization and sustainable development of natural geographical environment.

If the relationship between man and physical geography is not handled well, it will have a very bad influence.

Environmental pollution and waste of resources have caused natural disasters such as landslides and mudslides, and species diversity has been affected.

Xinjiang's natural geographical environment develops harmoniously, the region can develop sustainably, the resources are used rationally, and it is comprehensive, coordinated and sustainable. Rational irrigation, make full use of abundant oil and gas resources, and optimize and upgrade the industrial structure.

How to discuss the relationship between law and natural geographical environment? The legal environment and the natural science environment are inextricably linked and different. The legal definition of environment must be based on the definition of environment in natural science, especially the environmental legislation must follow the principles and laws of environmental natural science. Therefore, they are consistent in qualitative stipulation, and also define "environment" as affecting human life.

Modern Chinese reading "geographical environment, including natural geographical environment" and "8 o'clock: get up. Put on my green radiation protection suit, because I'm going to a green forest today.

9 o'clock: I get on a spaceship and go to another world, so I won't suffer from the greenhouse effect. Because it was a forest in the twentieth century, a green land of nearly one million square kilometers. If the air inside comes out, it will be gone in an instant.

10: study the great changes of the earth's environment and crust from millions of years ago to now in the geography laboratory of Greenland. Although some countries try to plant all kinds of trees and green the environment, many countries don't care much about the environment.

12: A meteor hit the geography laboratory in Greenland, and the person in charge here had to let us leave early. I went to the hotel by spaceship, where there were dishes from the 20th century. Melon. Fruit. composition

15: It's raining heavily, so we shouldn't treat it as acid rain. Because this rain is no different from ordinary rain. I immediately started waterproof clothing. If it weren't for the computer on my wrist, would I be able to tell the rain quickly?

18: Turn on the TV to watch the news and weather forecast. The weatherman said, "It will be sunny in Belfast tomorrow. London will be cloudy. "

22 o'clock: go to bed. Dreaming that green space was transferred to the earth. After further building the earth, will mankind still have a beautiful living environment?

The adverse effects of urbanization on natural geographical environment If this question is a multiple-choice question, you can only choose B. But I think there is something wrong with this question. All these four choices will have a negative impact on the urban environment. The adverse impact on the natural geographical environment is mainly reflected in some natural geographical elements, such as biology, atmosphere, temperature and precipitation, soil and so on.

Analyze the basic characteristics of Europe's natural geographical environment? Analysis on the basic characteristics of European natural geographical environment;

1, geographical location, latitude and longitude location:

Latitude and longitude: the mainland * * * is 36 ~ 7108' north latitude and 661'~ 9 34' east longitude.

Geographical location of land and sea: located in the west of Eurasia, bordering on Urals-ural river-Caspian Sea-Great Caucasus-Black Sea Strait and Asia in the east; North of the Arctic Ocean and west of the Atlantic Ocean, Europe is located on the west coast of the mainland, surrounded by the sea on three sides, which makes the Atlantic Ocean and westerly circulation have a far-reaching impact on the climate in Europe.

2. Contour lines and topographic features:

The continental contour is broken, the continent is wide in the east and narrow in the west, and there are many peninsulas, islands, inland seas and marginal seas, which is a major feature of European natural land. It is the continent with the lowest average elevation in the world, and is dominated by plains and prominent glacial landforms.

3, climate characteristics:

Temperate climate is dominant, and temperate maritime climate is remarkable. The south has a Mediterranean climate. The windward slope in the west of tall mountains is a region with abundant precipitation, while the inland of plains and peninsulas is a region with scarce precipitation.

4. Rivers and lakes:

There are many rivers, dense river networks, abundant water, good navigation conditions, long navigation mileage and many international rivers.

Lakes are widely distributed, especially in northern Europe and Alps.

How to analyze the natural geographical environment in regional geography? The regional geography of a region (including physical geography and economic geography) is always closely related to the geographical location and natural, economic and historical conditions of this region. As far as the natural geographical environment of a region is concerned, it mainly includes geographical location, topography, climate, rivers, vegetation and so on. In the analysis, we should first understand the characteristics of these environmental factors, and then analyze them. Generally speaking, the geographical position of a place can be analyzed from latitude and longitude, land and sea position and so on. Take Central Africa as an example. The longitude and latitude are between 3 "32" east longitude and 23 north latitude. South latitude is about 180, and the land and sea are adjacent to the mainland in the east and the ocean in the west. When analyzing the terrain of a certain place, we can think from the aspects of terrain ups and downs, terrain types and terrain distribution. For example, Zhong 1 Bu is a plateau-basin ecotone, including Congo Basin, eastern Chad Basin, all of Cameroon Plateau and a part of East Africa Plateau and South Africa Plateau. When analyzing the climate in a certain place, we can think about the relationship between the influencing factors, the distribution of temperature and precipitation and agricultural production. For example, the climate in central Africa is warm and hot, and the natural belts of climate and vegetation are symmetrically distributed in a north-south belt around the equator, that is, the central part has a tropical rain forest climate, and the northern and southern parts have a tropical grassland climate and a tropical desert climate. To analyze a river, we can consider the hydrological characteristics such as source flow, discharge, water level change, flood season length, sediment concentration and ice age.
