用生态经济学的理论指导我国生态农业的建设

生态农业是在世界和我国经济持续发展要求的背景下出现的一个新事物,农业生产的特点决定了持续发展首先在农业有了突破.生态农业的建立体现了经济与生态结合的要求，它的重要意义在于为我国农业现代化指出了新的发展方向。生态农业是在生态经济学的理论指导下建立起来的一种新的现代农业生产形式，它的发展也应当以生态经济学的理论为指导。为此应当明确树立生态经济系统的观念、生态经济平衡的观念和生态经济效益的观念，并明确认识农业的生态经济本质。

Results of the long-term field experiment IOSDV Jable at the beginning of the 21st century

The impact of organic fertilization and the level of mineral nitrogen fertilization on organic nitrogen and humus balance was studied in a long-term field experiment IOSDV Jable in central Slovenia (sub-Alpine climate, average annual precipitations 1345 mm, average annual temperature 9.5°C, heavy hydromorphic silty loam, umbric Planosols). During the period 1993–2010, precipitation increased significantly at an average rate of 19 mm a^?1; over the same period, average annual temperature increased by 0.025°C (l.f.). The increase in annual precipitation had a negative impact on the yield of all crops (maize, wheat and oats). Increases in mineral N rate led to increased yields. At the highest mineral nitrogen rate, farmyard manure (FYM) did not have a positive impact on yield in the investigated crops, although there was a positive effect of straw incorporation on the yield of maize and oats, and a negative impact on the yield of winter wheat. The organic carbon (Corg) level in the soil increased for all treatments, including FYM or straw and mineral N fertilization. The N content in the soil decreased in the treatment with no organic fertilization and no mineral N, and in the treatment with straw and no mineral N. Corg was increased in treatments with organic fertilization and the highest N rates and remained the same in treatments with moderate N fertilization. All C balances were negative.     

Pleistocene Park: Does re-wilding North America represent sound conservation for the 21st century?

A group of conservation biologists recently proposed to populate western North America with African and Asian megafauna, including lions, elephants, cheetahs, and camels, to create a facsimile of a species assemblage that disappeared from the continent some 13,000 years ago. The goals of this program, known as “Pleistocene re-wilding”, are to restore some of the evolutionary and ecological potential that was lost from North America during the Pleistocene extinctions, and help prevent the extinction of selected African and Asian mammals. Pleistocene re-wilders justify this conservation strategy on ethical and aesthetic grounds, arguing that humans have a moral responsibility to make amends for overexploitation by our ancestors. They believe that the flora of many North American terrestrial ecosystems has gone basically unchanged since the end of the Pleistocene, so re-wilding would help restore evolutionary and ecological potential and improve ecosystem functioning. This paper discusses some of the pros and cons of this proposal, including the ethical, aesthetic, ecological, and evolutionary issues, assesses its potential economic and political impacts on other conservation practices, both in North America and elsewhere, and reviews the realities of large mammal reintroductions. It is concluded that Pleistocene re-wilding with exotic species will not restore the evolutionary or ecological potential of native North American species nor extinct Pleistocene megafauna and their ancient ecosystems, but may instead jeopardize indigenous species and North American ecosystems. Resources would be better spent on preserving threatened organisms in their native habitats and reintroducing them to places in their historical ranges from which they were only recently extirpated.
