The degree of the low intensity of land use needs to be evaluated. The current method of comprehensive evaluation and grading by one index system has the limitations due to the existence of differences between regions and industries. This paper evaluates industrial land use intensity by Total Factor Productivity (TFP) analysis, which not only measures the intensity but also illustrates the ef-ficiency of input factors. This method is applied to the Beijing Economic-technological Development Area (BDA). A comparison analysis on factor use efficiency and input structure of capital and labor between industries is also carried out in the absence of a labor-income ratio.展开更多

It lies in the Liao River Valley, the Songhua River Valley and Nen River Valley. About 130 years ago, this region had rich natural grassland resources, was numerically 26.67 millions in hectare of grasslands. Since the last stage of Qing Dynasty, the grassland has been destroyed seriously in 3 times. Up to now, this region only preserved about 2 millions in hectare of the grasslands. In addition, 3.33 millions in hectare of the grasslands have changed from primary grassland to desertification, salinizatio-nalkalinization and degeneration grasslands in the form of patches of bare soil(their simple form of a name is'3 kinds of degeneration grasslands'). This paper indicaed that in any period both grasslands destruction and its restoration were relevant to economic changes and economic systems, particularly to market econmy in that time. The following agricultural economic-technological strategies have been applied to transform of retrogressive grasslands: ① to return reclaimed grassland as farmland to primary grassland in order to greatly increase-economic ecological benefits; ② to close desertification, salinizationalkalinization and degradation grasslands in the form of patches of bare soil; ③to develop grassland-agriculture for establishment of stable production bases of concentrated feed crops and coarse herbage crops.展开更多
