Abstract

Annotatsiya. Maqolada biologik xilma-xillikning ekologik piramida tuzilmasi, barqarorligi va faoliyatidagi o‘rni tahlil qilingan. Sonlar, biomassa va energiya piramidalari qiyoslanib, genetik, tur hamda ekotizim xilma-xilligining produtsent, konsument va redutsent darajalaridagi vazifalari yoritilgan. Xilma-xillikning qisqarishi piramida asosining torayishi, trofik pog‘onalarning soddalashuvi va oziq to‘ridagi uzilishlarga olib kelishi asoslab berilgan. O‘zbekistonning cho‘l, to‘qay, tog‘ va agroekotizimlari misolida xilma-xillikni saqlashning amaliy ahamiyati ko‘rsatilgan.
