【正文】 e current before they seep into groundwater and surface water as a buffer and absorb fertilizer and pesticide mode of agricultural production is beyond the capacity of the environment, agricultural production practices concern.This respect the differences of opinion to be considered for the economies of the economy, and the actual performance requirements of the sustainable shape, in large part is on the substitutability of the differences between the present and future view. For example, Christensen (1989) that, in most cases, manmade and natural capital can not replace each other. In other words, increase the yield of manmade and natural capital. Along this line of reasoning, Daly (1990), the requirements of sustainable development: (1) renewable resources (eg, fish, trees) and regeneration rate does not exceed the harvest rate, (2) (such as coal, gas, oil) nonrenewable resources, the price does not exceed the pace of development of renewable alternatives, (3) contamination rate does not exceed the absorptive capacity of the environment.The Solow (1992), it is possible to keep every type of capital and sustainable developments in the manmade and natural capital are allowed to replace each other the weaker definition. In this definition of sustainability, traditional measures of ine can be extended to consider the environmental goods and services as well as changes in the stock of natural capital. Weitzman, 1997, this expanded ine measures can be considered as indicators of sustainable development. Due to manmade and natural capital are allowed to replace each other, the only requirement is that of sustainable development, the overall capital stock, rather than each type of capital will not reduce over time.Second, a more sustainable agriculture, for exampleIn order to assess the sustainable development of . agriculture, we have the following trend of the indicators: agricultural productivity, soil erosion, the amount of groundwater, surface water quality, and groundwater quality and wetland conversion rates. These people can think of agricultural productivity, soil erosion, groundwater availability as there is some overlap between the ability to provide food for our present and future generations on behalf of service indicators. The quality of surface water, ground water quality, wetlands, and conversion rates can be seen as indicators of the impact on the environment and agricultural production. The difference between the productivity measures between output growth and input growth. If productivity growth is positive, then the same output with less input production. Figure 1 shows the growth of agricultural productivity in the . the mode. From 1948 to 1994, agricultural output growth in the average growth rate of percent per year growth. A slight decrease in the input is a use along with the output growth in annual productivity growth rate by percentage points while nonagricultural sector growth rate of percent. The price of agricultural products reflects this productivity growth. During the same period, farmers actually get the price of agricultural products fell by 50 percent
