摘要：
The relationship between the size and the number of plants in natural stands of vegetation has generally been taken to be governed by geometric considerations. On this basis, theory has it that average plant size scales as the -3/2 power of population density. If, however, energy use is taken as the determining factor, the exponent becomes -4/3 — which happens to be the exponent that applies to comparable relationships in animals.
