This paper proposes a kind of self-adaptive niching genetic algorithm (NGA) using probabilistic tournament selection.

Considering the premature phases and slow rate of convergence in evening of genetic algorithms,adaptive niche technology and adaptive probabilities of crossover and mutation are both introduced into the classical simple genetic algorithm,with one dimension theory of stress wave and finite difference method to identify the defects of pile.

The distribution pattern and ecological adaptation of Caragana microphylla,C. davazamcii and C.korshinskii;

Memory formation and ecological adaptation in insects;

Research on structure of leaf epidermis of two species of Flos Lonicerae by SEM and its ecological adaptation;

This paper summarizes general anatomical features of such different nutritional organs as roots,stems and leaves on the basis of having systematically dissected different genera and species of mangroves,anddiscusses the relationship between the anatomical structure of mangroves and their ecological adaption.

However,the former research was unfolded mainly on the ecological adaption of culture.

Spatial distribution and ecological adaptability of wetland vegetation in Yellow River Delta along a water table depth gradient.;

Differentiation in morphometrics and ecological adaptability of cotton and cucumber biotypes of the cotton aphid, Aphis gossypii (Homoptera: Aphididae);

This research attempted to study systematically and practically the issues of regional ecological adaptability of water in some major crops in upper reaches of Hanjiang river by applying field water balance model, and using GIS technical and risk index of water deficit.
