Environment: the total of our surroundings
• All the things around us with which we interact: Biotic vs. Abiotic
• Living things
• Animals, plants, forests, fungi, etc. • Nonliving things • Continents, oceans, clouds, soil, rocks • Our built environment

谢谢！
• last year, my dormitory went to Suzhou classic garden. It is an antique garden with beautiful flowers and various trees. It is the representative of Chinese garden. And it is decorated by manmade rivers, different kinds of rockeries, the unique bridges and so forth. Once you enter the garden, you will find you just like a pure man in the ancient. You may even believe you are not living in the modern city but the peaceful area without armored concrete, chaos, benefits and so on.
It is China’s largest Theme park of the fourth generation, consisting of 15 main parts. And my favorite part is the “World of Universe”----the perfect application of high technology.

Temperate grassland: also known as prairies or steppes, are widely distributed over temperate parts of the world. Climate: As with deserts, the major factor that contributes to the establishment of a grassland is the amount of available moisture. Grasslands generally receive between 25 and 75 centimeters of precipitation per year. These areas are windy with hot summers and cold to mild winters.

广东工业大学 环境科学与工程学院
Succession The communities proceed through a series of recognizable, predictable changes in structure over time is called succession. Primary Succession Primary succession is a successional progression that begins with a total lack of organisms and bare mineral surfaces or water. Terrestrial Primary Succession Aquatic Primary Succession Secondary Succession An original community is a successional progression that begins with destruction or disturbance of an existing ecosystem.

CHAPTER ONE Environmental Interrelationships
OBJECTIVES After reading this chapter, you should be able to: Understand why environmental problems are complex and interrelated. Realize that environmental problems involve social, political, and economic issues, not just scientific issues. Understand that acceptable solutions to environmental problems are not often easy to achieve. Understand that all organisms have an impact on their surroundings. Understand what is meant by an ecosystem approach to environmental problem solving. Recognize that different geographic regions have somewhat different environmental problems, but the process for resolving them is the same and involves compromise.

The equivalent sound level of environmental noise in urban area is between 53.5 decibels and 65.8 decibels, and the national average is 56.5 decibels (area weighted). Among the 43 cities, 33 have sound levels over 55 decibels, among which, the equivalent sound levels in Datong, Kaifeng and Lanzhou are over 60 decibels, and the pollution is heavy.
The Yellow River is under the double pressure of pollution and disconnection. 66.7% of the rivers monitored were of class Ⅳ water quality. The main pollution indexes are ammonia nitrogen, volatile phenol, permanganate index and biochemical oxygen demand.
2.Water pollution
According to the State of the Environment Bulletin of China and the report of the Ministry of Water Resources, in 1997, the seven major water systems, lakes, reservoirs, and parts of China's groundwater were polluted to varying degrees, and the proportion of river pollution was higher than that of 1996. In the dry season, the length of polluted rivers increased by 6.3 percentage points, and the periods of high water supply increased by 5.5 percentage points. Of the more than 50,000 km of rivers assessed, 42 were polluted, of which 12.2 were seriously polluted

Community: is an assemblage of all the interacting populations of different species of organisms in an area. Climax community: The relatively stable, long-lasting community is called climax community.
Savanna : Tropical parts of Africa, South America, and Australia have extensive grasslands spotted with occasional trees or patches of trees. This kind of a biome is often called a savanna. These areas of the world are typically tropical, with 50 to 150 centimeters of rain per year. The rain is not distributed evenly through-out the year.
CHAPTER THREE Kinds of Ecosystems and Communities
OBJECTIVES After reading this chapter, you should be able to: Recognize the difference between primary and secondary succession. Describe the process of succession from pioneer to climax community in both terrestrial and aquatic situations. Associate typical plants and animals with the various terrestrial biomes. Recognize the physical environmental factors that determine the kind of climax community that will develop. Differentiate the forest biomes that develop based on temperature and rainfall. Describe the various kinds of aquatic ecosystems and the factors that determine their characteristics.
