[Environmental cost of rice production in Dongting Lake area of Hunan Province].
To evaluate the environmental cost of rice production is of significance for the sustainable development of agriculture and the set-up of green GDP accounting system. In this paper, the environmental cost of rice production in Dongting Lake area, one of the main bread baskets in China, was evaluated from the aspects of pesticide pollution, chemical fertilizer pollution, greenhouse gases emission, plastic film persistence, paddyfield gleyization, and polderization. The results showed that in 1999, the total environmental cost of rice production in this area was 41.91 billion yuan, equivalent to 26.8% of its total agricultural production value, or 28.5% of the gross output of its planting industry. For the sustainable production of rice, the strategies for decrease environmental cost intrinsically were put forward.
