话“径”说“园”——来自现象学语境中的解读

在现象学语境下对中国古典园林路径进行解读,从物我关系角度探讨园林路径之＂源＂起;以生命轮回意识看园林路径＂圆＂之循环模式;透过园林路径与＂天地人神＂四者之＂缘＂探寻其空间赋形机制;由人对自身存在的时间阐释揭示园林路径对于时间的＂援＂引,旨在以现象学理论重新审视中国传统哲学、文化及建造意识,反思其本质,并从中发掘创作灵感,对当代建筑及园林创作具有跨领域、创造性的现实指导意义。

Analyses of spatial patterns and population processes of clonal plants

The nonrandom spatial structure of terrestrial plants is formed by ecological interactions and reproduction with a limited dispersal range, and in turn this may strongly affect population dynamics and population genetics. The traditional method of modelling in population ecology is either to neglect spatial pattern (e.g. in transition matrix models) or to do straightforward computer simulation. We review here three analytical mothods to deal with plant populations in a lattice-structured habitat, which propagate both by seeds that scatter over the whole habitat and by vegetative reproduction (producing runners, rhizomes, etc.) to neighboring vacant sites. [1]Dynamics of global and local densities: Dynamical equations of population density considering nearest-neighbor correlation (spatial clumping) are developed as the joint dynamics of global average density and local density (comparable to mean crowding) based onpair approximation. If there is a linear trade-off between seed production and vegetative reproduction, the equilibrium abundance of the population may be maximized by engaging both means of reproduction. This result is accurately predicted by the pair approximation method, but not by mean-field approximation (neglect of spatial structure). [2]Cluster size distributions: Using global and local densities obtained by pair approximation, we predicted cluster size distribution, i.e. the number of clusters of occupied sites of various sizes. [3]Clonal identity probability decreasing with distance: Multi-locus measurement of allozymes or other neutral molecular markers tells us whether or not a given pair of individuals belong to the same clone. From the pattern of clonal identity probability decreasing with the distance between ramets, we can estimate the relative importance of two modes of reproduction: vegetative propagation and sexual seed production.

价值寻求与感性生命的错位--对市场经济下中国小说创作路向的反思

不同于政治文化语境中的小说创作,市场经济下的小说创作显示出了另一种特征,前者因服务于意识形态而忽略了感性生活形态,后者则将价值寻求消隐在了感性生命的张扬之中,能否将生命体验与精神追求结合在一起是当下小说创作突破的关键.
