Kirish: gidronimlar toponimiyaning eng barqaror unsurlaridan bo‘lib, qadimiy aholi va xo‘jalik faoliyati izlarini saqlab qoladi. Buxoro vohasida ariq, arna, ariqcha komponentli mikrotoponimlar sug‘orish tizimining tarixiy ahamiyatini aks ettiradi. Maqsad: Buxoro vohasidagi gidronimik mikrotoponimlarni semantik va etimologik jihatdan tasniflash hamda ularning sug‘orish terminologiyasi bilan bog‘liqligini ko‘rsatish. Materiallar va metodlar: toponimik tahlilning tavsifiy va qiyosiy metodlari qo‘llanildi. turkiy leksik qatlam va sug‘orish terminologiyasi bilan bog‘liq ma’lumotlar tarixiy manbalar va dala materiallari asosida o‘rganildi. Natijalar va muhokama: Rabotisariq (“qal’a ariqlari”), Odoqariq (“Odoq yonidagi ariq”), Bashariq (“asosiy ariq”), Arna va Tarnavut kabi nomlar qadimiy suv xo‘jaligi amaliyotlarini saqlab qolgan. semantik tahlil bu nomlarning qishloq xo‘jaligi va aholi hayotidagi ahamiyatini ko‘rsatadi. etimologik jihatdan ular turkiy ildizlarga borib taqaladi, stilistik jihatdan esa kollektiv xotiraning madaniy belgisi sifatida namoyon bo‘ladi. Xulosa: Buxoro vohasidagi gidronimik mikrotoponimlar sug‘orish tizimining tarixiy va madaniy ahamiyatini mujassam etadi. ularning semantik va etimologik xususiyatlari vohaning til va madaniyat merosini o‘rganishda muhim manba hisoblanadi.
Introduction: hydronyms are among the most stable elements of toponymy, often preserving traces of ancient settlement and economic activity. in the Bukhara region, microtoponyms with components such as ariq, arna, and ariqcha reflect the historical importance of irrigation systems in shaping local geography and culture. Purpose: to classify and analyze hydronymic microtoponyms of the Bukhara oasis, focusing on their semantic meanings, etymological origins, and relation to irrigation terminology. Materials and Methods: the study uses descriptive and comparative methods of toponymic analysis. linguistic data are drawn from field materials and historical sources, with attention to the Turkic lexical layer and its integration into irrigation-related terminology. Results and Discussion: findings show that names such as Rabotisariq (“fortress canal”), Odoqariq (“canal near Odoq”), Bashariq (“main canal”), Arna, and Tarnavut preserve evidence of ancient water management practices. the semantic structure of these names highlights the role of canals and irrigation in sustaining agriculture and settlement. etymological analysis confirms their connection to Turkic roots, while stylistic examination reveals their function as cultural markers of collective memory. Conclusion: hydronymic microtoponyms of the Bukhara region embody the historical and cultural significance of irrigation systems. their semantic and etymological features demonstrate the continuity of water-related terminology in local toponymy, making them an essential resource for understanding the linguistic and cultural heritage of the oasis.
