Abstract

Abstract

By using seven parameters such as the growth rates of urbanization, per capita GDP, yield per mou of grain crops, consumption of pesticides and chemical fertilizers and decreasing rate of cultivated land and per capita cultivated land, the authors proposed four indicators: the land utilization intensification coefficient, the land consumption redound coefficient, the land production coefficient and the land contamination coefficient. According to the indicators, a new model—trendline-equality line (TLEL model) is established to evaluate the quality and sustainable utilization of land resources in different areas in each development period, such as in Meizhou, Guangdong Province during the 1990s. The result indicates that the indicators and the TLEL model are appropriate for macroscopical assessment of the actuality and trend forecasting of the land resources utilization.
- quality of land resources,
- sustainable utilization,
- assessment indicator,
- trendline-equality line model
